I would take time to appreciate the way you taught. A must watch video for the ones, who wishes to learn the Static Structural Analysis using Ansys, but can't find it easy to do. This video, takes you through all the basic concepts required for the Analysis and that too without over exaggeration, and by the end of the video, you realise that you have understood it and ready to go!!! Thank you so much Sir. Keep up the good work. 🔥🙏
Excellent tutorial, smoothly show examples of crucial know hows in performing efficient FEA computation. A tutorial on the character of various contacts and their control, especially when plasticity occurs at contacts would be very appreciated.
Amazing tutorial man! Thanks. You really master Ansys Mechanical. At 10:41, maybe if you add the displacement on both sides you get something closer to 0.3 mm. (Idk if you were already considering it)
Thanks for the tutorial. It helped me a lot! If you can explain why you chose a symmetric behavior for the contacts would be great. Thanks again for sharing this
+Santi GM Hey no problem! To keep it simple, symmetric behavior gives lower penetration however it is more computationally expensive. It also provides contact results on both surfaces of the geometry.
Great tutorial...Can I use the same concept for my model, which has an adhesive joint and a screwed joint, to check if the adhesive gives away as I tighten the screws? Also I would love to see how the reliability (time related failures) of a model can be simulated using ANSYS. Eg., If I were to simulate environmental Stress Cracking by putting the part in a humid oven, after how long the weakest member is going to crack. Good job!
excellent tutorial, could u please make tutorial about how to overcome convergence issues in multibody analysis, how to read the solver output, time, force criterion plots, thanks
@@drdalyo Hi DrDalyO, can you please make a tutorial on modeling in Design Modeler? Specifically, how do you create multiple bodies/parts and make sure that they are at the correct location?
Hi Doc, could you please go ahead and post a video on how to change the position of pretension on the bolt? Also, I'd really love to know what the symmetry/asymmetry in the contact area means, tnx by the way, the tutorials help alot. ;)
Thank you so much for your tutorial video, this also guide me some suggestion in my work. But I still in my trouble. I have some case for static analysis. If there are 3 components. First, element 1 make element 2 deformation, then element 2 to contact with element 3 and transfer moment. All contact is frictional. I try some option in contact, but program didn't give me any suitable results
Very nice videos!!! I have the following questions: 1. Let's say that you have some deform-able bodies and you need to connect through Rigids, How to we do that in ANSYS? 2. Is there any option to transfer the loads, say force or pressure on a surface through a contact surface without physically connecting it or is there any equivalent options. 3. can we plot shear force/ Bending moment diagrams on a 3D models; as in your 1st video on 3D beam.
+Naveen Anan you can change the option from deformable to rigid in the Geometry branch in the outline for each body. Yes there is something called Connections to create contact. Moment and shear diagrams are for beam elements only, not for general 3D elements
Do you have a tutorial regarding how to see the load distribution after apply a force/pressure on a surface or how force reacting each other among different components? At ansys When we apply a force to a surface, the load is even distributed I assume? Can we apply uneven distributed load to a surface at Ansys? Thank you very much in advance.
Here is a tutorial where I use a varying load: th-cam.com/video/mAZKGNcDDvs/w-d-xo.html To see shear and moment results, you would need to use beam elements, and use the beam results tool. You can also see reaction force results if you change the scoping method
Hi DrDalyO, This is indeed a very helpful video. Thank you very much. But when I applied bolt pretension it was not centered and my results are different from yours. How can I make the bolt pretension centered?
Great video.i am now doing the simulation about the bolt thread .i got some information about it from the ANSYS mechanical .but i cant understand it .could you do a video about it .THANKS
+刘胜杰 There is actually a new function in ansys 16 i think that can do bolt threads for you (meaning you dont need to model the actual threads) maybe check that out. If not I could look into doing a tutorial on it. Its a good topic. Thanks for watching! please subscribe
Great Tutorial! I have a problem of a beam supported on a concrete floor. This beam has no inertia to distribuit the nodal force equally along its lenght, and I want to know which area of the concrete floor that is supporting the load. How can I model it? Can you make a tutorial video regard this subject? Thanks.
Great video! I am applying frictional contact, however loading perpendicular to the friction (bending). Can there be friction and keep the body fixed ?
I like your tutorials. Please keep on sharing. I can give you some struggling problems. And I have a question about this video, Can you explain the reason why you choose Contact Behaviour as Symmetric? What if I choose "program controlled"? Thank you so much.
+Ufuk Bilgin program controlled will choose the best default method, it wont affect the results in this case. you can do some research on this in the help. (ex. symmetric vs asymmetric), basically symmetric will show you results on both surfaces on the contact, and asymmetric will only show on one surface. asymmetric is usually less solve time.
Hello, thanks alot for this tutorial. I have just one question, for bolt pretension, you went for adjustmet but didn't explain what does it mean? like if i go for Load, does that mean torque applied on bolt, while we are fastening it?
Thank you very much Dr.Dalyo. Very helpful tutorials. I wanna ask you I am modelling wall using masonry bricks and I want to add Interface connection (e.g INTER193 : 2-D 6-Node) between the faces of the brick. I don't want to use the automatic contact provided by the Ansys. If you have the command code I will be very thankful
Greetings! Thanks you very much for your videos! It's all really helpfull. How do you think to make tutorial about construction made from beams and using the beam-element (line-body , i guess) to analize it? Or using different kind of elements in different cases and how to change it in WB. I think, it's the base knowledge and it will be really helpfull, espetially for beginners.
+skullheaddd1 I could add a tutorial like that to my list. I was thinking of doing a truss example which contains line bodies. In geometry modeler you could just draw lines, and apply a section to the line and create a line body. Video to come.
+DrDalyO The truss example would be just what is needed. "In geometry modeler you could just draw lines" - but how can I do the same thing when imporing geometry from SolidWorks, for example? How can I convert solid bodies was modelled in SW to line-bodies in WB?
+DrDalyO Thank you for this video. I am learning a LOT VERY quickly, so these videos are DEFINITELY helpful/useful. I did have one question though - you had mentioned that you can create a coordinate system and change the bolt pretension cross-section location. Can you please create and upload a video showing us how to do that. That would be greatly appreciated. Thank you.
+Sravankumar Nerella I think it should be very similar to this example. Maybe start by importing the model and using the techniques i showed regarding contact with yours and see where you go. Let me know!
very nice tutorial SIR. Was very helpful indeed i just have a small doubt. I need to design and evaluate a double skinned composite walls with shear studs. So can i do it in ansys or must i use any other software. If i can use ANSYS itself how can i start or proceed
What type of contact should i use if one plate is grouted in foundation and second plate is bolted to the grouted plate. Second plate is a footing of a frame. Bolt is torqued. Could you please explain what contacts and boundary conditions should be applied? Thanks
Very nice video, I have a question though: what if I need to evaluate the life? On the model I want to set some bolt pretensions and some external loads. Only the external loads should determine the cyclic load, while bolt pretensions should be a constant. How can I set this in the fatigue tool? Or maybe this is automatically done by the software? Thank you in advance
Thanks for your tutorial they are really useful! Mesh question: Some guys (in DM) use in to divide model (slice material) in “regular” bodies and form with them a new part, in order to obtain a more regular mesh. For example consider our bolt and slice it in one minor diameter cylinder and one greater diameter cylinder: or our “C” bracket as a part made of 3 “body” plate. What do you think about it? it makes sense or maybe it is and old habit who comes by older or different program? Corner and edge question: Some guys use to delete fillet radius from model in order to obtain more regular mesh (like above) and reduce computational
slice is often used for the complicated model, mostly we just care about the high stress location, so sometimes we simplify the model to reduce the calculation time
Great videos! Very helpful! But isnt 0,2 a bit to small for frictional coefficient between steel? When I make the coefficient bigger my solver solution do not converge.. :(
+Tom Glansholm well if its lubricated no. But if not then ya would be higher. In most cases it wont change the results significantly depending on where is your point of interest. If you really focused on the contact results then ya, put a more realistic value. Also any value above 0.2 i believe in Ansys makes it more difficult to resolve and takes longer, hence your convergence problems. You might have to make smaller substeps to solve. Good luck and thanks for watching!
Thanks again! I am a engineering student and havent taken any courses in advanced FEM yet so this is just for fun. But im interested of the effects of having a frictional contact, not the contact itself. Like if you have two plates and a bolt connecting them. The frictional forces prevents shear stress in the bolt if you have the bolt pretensioned(? english) so that normal forces appear between the plates. Maybe some other approach is better?
Thank you for your videos sir, i'm really appreciated. Do you have any ansys video that is related to SMA(Shape Memory Alloy) properties or not? i'm so curious of how to apply these property in ansys.
Dear DrDalyO. At 8:44 You said very important thing about location of pretension cut. I have long bolt with pretty high pretension and I am getting large step in deformation of my bolt. Could You possibly provide any solution to get rid of this unrealistic deformation? Thank You for sharing knowledge.
Hi, I just wanted to ask why you didn't switch on gravitational load? I see that without it coeff of friction doesn't affect the model at all. It's kindof totally confusing at the moment for me. Looking forward to hearing your idea about this
Coeff of friction should not have anything to do with gravitational load. If the friction is not working, you should investigate the contact not gravitational load.
hi, thanks for you video, usually the diameter of the hole in the bracket is slightly bigger than the bolt, so there is a gap between the two cylinder face, will this still be able add frictional contact?
I would take time to appreciate the way you taught.

In general, how do we know what friction coefficient to use, especially if it’s thread on thread.
hi, thanks for you video, usually the diameter of the hole in the bracket is slightly bigger than the bolt, so there is a gap between the two cylinder face, will this still be able add frictional contact?
It pretty good explaining but little too faster while selecting commands and proportions plz do it slowly because we r learners ...👍
Force in bolt after adding external load should be lower than pretension force....
