Hi Faisal, Where do I get the properties for Ti64 material?
Not sure, maybe from a research paper
hi thanks for the video. I would like to konw how to set the amp-for pin in the edit boundary concidtion part ?
Thank you for sharing this video Faisal! Much appreciated for the explanation of the steps and why we should do it, not just uploading a video. Subscribed! and looking forward to see more videos from you :)
Thank you very much for the appreciation :)
Great !! Tutorial on Modeling of XFEM fatigue crack propagation in ABAQUS using Direct Cyclic approach
Did you use c1,c2,c3,c4?
Yes. I can send you the files if you send me an email at fysalqayyum@yahoo.com
I am working on mixed mode fracture in concrete using XFEM method. For that the crack would propagate at some angle not straight like in your case, and that is because the fracture energies are different for different modes and hence their contribution vary as the crack propagates with time. I am curious about the fact that how one would know which region and to what extend one has to select to make sure that the crack propagate in that region. I mean how you new that you crack will propagate along that straight line, it could have, practically, gone anywhere in that plate.
do you have the answer for this? Cuz im also curious 😆
thank you for your video. i have a question, what is the amp-for pin??(at the boundary condition)
I think it was just defines but not actually used in the simulation
Sir, what is the mesh and element type used? For me it gives the error that "output strain request is not available for selected element type"
I am not sure why are you encountering that error. You can send me an email at fysalqayyum@yahoo.com and I can send you the files for deeper analysis
thank you for the video.please share us rolling contact fatigue analysis on train wheel- rail using abaqus
Have not simulated that before. It is tricky problem as the strain accumulates in the material over time due to rolling contact fatigue and results in material hardening and eventual failure.
Size of crack and plate do not seem to be compatible. Can you plz share the geometric details?
Yes, you are right, they are not compatible. I scaled up the simulation results in this case for better visualization of the phenomenon occurring.
Would you like to share a tutorial for Concrete smeared cracking I hope it will help a lot to many people?
I have not worked on that before, if you have an example case, i would love to collaborate and share the video for public reference
Salaam Faisal sb , I am Himmat from taxila "Modeling XFEM fatigue crack propagation in ABAQUS using Direct Cyclic approach" I have tried to simulate this model but crack did not ove farward Can you share the file?
Yes I can. Write me an email at fysalqayyum@yahoo.com
@@FaisalQayyum THANKS FOR REPLY I HAVE SENT YOU AN EMAIL ALREADY
I did not receive your email
great Video! but how to deal with these outputs? Furthermore, does direct cycling not define crack growth criteria?thanks a lot
How to deal with what outputs? No, there is no crack growth criterion in direct cycling step
Hi, can you please tell what is the amplitude for pin for this video
Which pin ?
poor tutorial for meshing, assembly
@@maxtek25 I agree, because it's not a video about meshing or assembly.
Great! Could you please send me the values of Fraction Criterion (type=fatigue) that you have used (c1,c2,..,G)?
I can share the files with you if you can send me a request on my email address, fysalqayyum@yahoo.com
HI, do you know how to define Fraction Criterion (type=fatigue) in Abaqus? i couldnt find one. i find the one in interaction property manager, but it only shows VCCT and enhanched VCCT
Sir, could you please send me the cae file, followed your steps but not not able to get the same results.
Yes I can, please share your email address
Thanks in advance
Hi, Thanks for the video. Have you ever tried to modify the keywords to apply the direct cyclic by defining c1,c2,c3 and c4?
Not yet
Hi Esra, were you able to define it?
Hi, for some reason I cannot see the crack growth when my model. Can you share the file?
Hello dr i have sent u on your yahoo mail , thanks in advance
How to track the crack length of each cycle??
I think you will have to measure it manually using available post processing tools. If you want to learn more about that please refer to my video : studio.th-cam.com/users/videozCVkfmAmwAM
why crack propagation is showing not available in direct cycling method to me
if anyone has idea please let me know
I'm not sure why
I am also unable to get crack propagation in direct cyclic but using static general I got...
same for me, do you have the answer already?
How can i determine the rate of crack growth as a function of time or load?
Is there any way to track the forward displacement of the crack tip?
Very helpful video
hi can you make video on composite material
Hello, Thank you for the comment. There are many types of composites and each would have a varying modeling technique. Which one are you specifically talking about?
@@FaisalQayyum polymer composite where matrix may be thermosetting or thermoplastic polymer and reinforcement may be glass fiber,carbon fiber carbon nano tube(cnt) etc and may or may not be filler material
Nice video
How to find fracture energy..?
Hi! Can I use the same approach on a 3D CT specimen? I have been trying this approach for the past couple of days but can't get the simulation started as I can't understand how to define debond conditions in order to use Paris Law constants
It would be great if you can please explain the issue in detail. I cannot suggest anything from the information you have shared
@@FaisalQayyum thank you for getting back so fast! Basically I have to simulate crack propagation on a 3D CT specimen subjected to fatigue with R=0.1. This crack growth must be done using XFEM and fatigue criterion must follow Paris Law with VCCT constants (c1, c2, c3, c4, delta G ,etc..) that I already have. After simulating crack propagation I have to take from Abaqus a da/dN curve and compare it with experimental results. I would be glad if you could help me to the best of your ability. If its easier for you, we can talk by email
@@NikitaKaminskyy I have never done exactly this kind of research work before, but seems doable. I have a lot to do these days so will not be able to respond in detail, but, you can contact me on fysalqayyum@yahoo.com for any specific issues and I would try to help to the best of my knowledge.
th-cam.com/video/FeHR1UjW9vk/w-d-xo.html made a new video on 3D cracks, maybe it will help
@@NikitaKaminskyy your question is very similar to what I am now trying to figure out. Have you succeeded in finding the answer and creating such a model?
Can we do fatigue analysis using static general by mentioning amplitudes instead of direct cyclic approach....
Did you got the answer
Great
Thank you
Great!
Thank you :)
Can you explain what data we can get from that simulation for the next video ?
Sure, can be done... Thank you for your suggestion.
@@FaisalQayyum can you find crack length using that simulation?
Yes sure we can. By measuring the crack length using 'querry' option.
@@FaisalQayyum I followed the steps you showed but it didn't work, i dont know why. want you sent cae file , please ?. fianace21@gmail.com
Yes I can share the cae files. Hopefully next week as I'm on holidays these days
Thanks for this video. What amplitude you have used for fixed boundary conditions?
And If you have any reference for the value(42200) that you have used as fracture energy please share.
I did not use any amplitude for the fixed boundary condition. This is just an example video and 42200 was just an exemplary value which I used here.
@@FaisalQayyum thanks for you quick reply. I followed each steps, shown in this video. But crack is not propagating. Can you send me the cae and njl file? It will be helpful for me.

@@barman5186 yes I can if you write me an email at fysalqayyum@yahoo.com
@@FaisalQayyum ok thanks 🙏
Please guide me to carryout fatigue delamination growth simulation in DCB specimen
Heyyy, Can you please explain your problem more ?? It will be great if you can please share it a bit more specifically on email.
Do you want to run a simulation model similar to what has been shown in this simulation?
onlinelibrary.wiley.com/doi/full/10.1111/ffe.12566
I want to simulate the fatigue delamination growth resistance in presence of fiber bridging
2D and 3D model done. 3D model have z pins. Now fatigue to be applied for 100 cycles
Please guide and support
