Mostafa Ismail after the damage of the glue between blocks , the blocks will have a friction I think, so, I think you should define tangential behaviour also .
Hi Mostafa, I am getting error that "The interaction "Int-1" references a contact property (CohesiveProp) that contains the damage or cohesive behavior option. These options cannot be specified with General contact (Std) interactions. Ok to continue with the input file generation ? "
Hi Mostafa, Why you defined contact pair between the 2 blocks and not tie constraint ? There appears to be sliding contact between the 2 blocks. But what if we have a composite structure which needs tie between the sandwiched layers. Do we still use the general contact in that situation or can we use this fake property even in tie constraint ? Regards,
Thanks for the interesting video but how I can model crack propagation in two attached members with and the crack started in the first member and is going perpendicular through the adhesive layer and finally propagate in the second member
First of all, very much thankful for the video. What kind of Step have you used in this? Because While submitting the job I am getting error message saying cohessive behavior cannot be used if interaction property is global contact property in general explicit model
Thanks a lot for the video. Really well explained. My question is will the same procedure of defining the cohesive surface interaction work if we have a general static step instead of a dynamic explicit one?
hi, my friend, i need making the mode soil and appear some problem THE SLAVE SURFACES ASSEMBLY_S_SURF-14 AND ASSEMBLY_S_SURF-12 INTERSECT EACH OTHER. THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_M_SURF-16 AND ASSEMBLY_M_SURF-12 THAT ALSO INTERSECT EACH OTHER. IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM. IF BOTH ARE *TIE PAIRS, THE REDUNDANT TIES WILL BE REMOVED AUTOMATICALLY. IF ONE PAIR IS *TIE AND ANOTHER IS *CONTACT PAIR, REMOVE ONE OF THEM.

Thank you for video. can you please provide more details of damage criteria details(ref.) how we can take Knn,Ktt etc values.
Thanks for your helpful video！
I have a question that does the fake property work in the simulation? Or both of them works?
Hello! Thank you so much for the amazing video :D
Is it possible for me to contact you via e-mail? Thank you.

Is cohesive behavior only for Dynamic Explicit analysis ? or can we use for static general analysis also ?

Thank you very much for the method. It really works.
Thank you. I struggled with this for a long time

Hey, do you know what unit he’s using? علاء العزاوي
Interesting and teachable video go ahead!
thank's i need an example for fsw
How can I determine the damage constants for cohesive elements?Thank for the video.
experimentally with DCB and ENF test
Thanks.
pls upload soil structure interaction tutorial.
Hello, do you know what unit he's using?
@@yongqi914 I Think that's Pa, M, N.
Jaspe Engenharia Thank you so much
thanks for the video. could you make tutorial of zero thickness cohesive elements?
Check this one:
th-cam.com/video/bDJkS0OoM7A/w-d-xo.html
How to apply the same in Abaqus/Standard? I tried to the same but Abaqus told me that is not possible for std.
I mean to define cohesive contact as general contact.
@@gianlucaborgna1638 Do you know what unit he's using? in mm or m? Thank you
