a new video with element deletion and damage evolution based on hashin damage is here:

Thank you for everything
I hope you provide a vedio about subroutine
I have updated to Timecodes for a better overview:

If there are some aspects of the video which need more details or explanations, let me know.
Sir can you make video for 3-point bending test using composite laminate plate of different ply with sold model?
@@zahidrana6200 can you link a reference or geometry?
@@hnrwagner
Plz share your mail. so i will send the geometry file
@@hnrwagner I have mailed you.
Thanks for the vedio, very helpful.
It would be very beneficial if you could make a video on ´´drilling CFRP composites´´.
Thanks and regards
what kind of tutorial you want to see next ? comment below !
Dear Prof. Wagner, is it possible for us to use FE2-Multiscale for solving this problem in Abaqus?
Could you please make a ballistic impact on the thick composite plate consists of 4 plies (0-90-0-90 degree of rotation) thank you so much
Hello prof! can you tell me where you got these data from?
@@sajjidhasanasifpantho4031 the data were send to me by a viewer
where can i get these data sets Prof? I have found several links & papers but are those trustworthy?
Sir, please make video on how to model spar wingskin adhesive joint with composite materials
very useful video sir. Would you upload a video on progressive failure analysis of composite laminate with a hole using Puck, Max stress, LaRC or other failure criteria through UMAT subroutine? Thank you.
in part already done here:
th-cam.com/video/Ctqa66QDLl0/w-d-xo.html
Great video sir. Could you make a video on the machining of this composite plate?. There's not much work available in this regard. Would be of great help. Thank you
There are already some videos on this topic on youtube, also, I dont have the expertise for this kind of simulation
Thanks Dr. Wagner for wonderful videos. If plies are not of the same thickness how to specify relative element thickness in that case and Does it depend on mesh also in that case.?
good question, i will take a deeper look into this problem.
Thanks for the video, what section are you using here?
here is the reference (Open Access) for the material data is given here:
www.mdpi.com/2073-4360/12/1/157
Elastic Properties, Strength values and Fracture energies...
Thank you for the video.
it would be really beneficial if you can stregnthen a steel pipe with carbon fiber reinforced polymer under bending for example and plot load vs deflection curves.
Thank you
Why did you change the rotation angles back to 0? Isnt the original orientation what makes it quasi-isotropic?
How to use Hashin criterion to delete elements under low velocity impact? Thank you for your reply
here is an example with element deletion:
th-cam.com/video/SfbY2qAudjo/w-d-xo.html
Thanks. If only the matrix fails in tension or compression, can the element be deleted for the Hashin failure criterion?
Yes, i am working currently on an example for it
here is an example with element deletion:
th-cam.com/video/SfbY2qAudjo/w-d-xo.html
Dear Dr. can I use this method to represent the RC beams strengthening by CFRP or GFRP sheets???
Think so
BTW, normally for damage to be occurred should not it be higher than one? Here damage is not occurred? Also, why you used those DOF for rp i do not get it?
Thanks for your comment.
It is stated in the video that if the criteria equals or exceeds 1,failure occurs according to hashin.
I am working on an update of the video which will include element deletion, so the damage is more obvious. Also it will include more details on modeling and why. Thanks for your advice
For the equation constraint to work you need to define the dof of the intended loading.
@@hnrwagner Thank you so much. Just could you explain briefly that equation constrain? when you input 1 what does that mean?
@@Pishgul it is well described here:
abaqus-docs.mit.edu/2017/English/SIMACAECSTRefMap/simacst-c-equation.htm
Can any one plz respond what will be the damage evolution and stabilization criteria values in abaqus for HB26 material
Will be greatful
those values have to be determined by material tests(tension / compression / ...), see abaqus-docs.mit.edu/2017/English/SIMACAEMATRefMap/simamat-c-damageevolfibercomposite.htm
@@hnrwagner sir, plz do ballistic impact on 3d composite using hashin criteria... With preferably HB26 or and other material... Kindly do
I have seen your static 3d analysis with hashin criteria
If possible kindly send me damage evolution and stabilization criteria of HB26 or some other materials
Thanks for your kind reply
hello sir. Is there a way to find the matrix ABD from Abaqus? I want to see if the ABD matrix I have is the same as the ABD matrix of the model I made in Abaqus.
Don't know, sry
Thank you and I have one more question. In the buckling analysis of a composite plate, I have obtained the eigenvalue of the first buckling mode. Is it obtained by multiplying the eigenvalue by the pressure applied to the buckling load plate?@@hnrwagner
@@user-vp6sq4kb9l I would apply the load with an amplitude of 1 , then the eigenvalue is the linear buckling load
Which materiel ????
Sir, from my point of view you do the videos fast and it seems that you just want to finish it. It is better to slow down somewhat. Thanks
Thanks for the advice, can you please elaborate or give an example, that i can improve the videos. Thanks
@@hnrwagner Sorry sir it might be presumptuous but even for me who has worked with abaqus for around 6 years the videos seem to be fast. For example, you just choose the options without any specific elaboration. I just asked two questions in my comments for this video. If you look at them and turn back to see the videos you would notice that you just choose and continue. By the way your voice is also hardly heard!
