Abaqus - Creating and Modelling Cohesive Elements

[@zhouchengsu1431]

The load on the left block is not transferred to the right block because no interaction between the cohesive layer and the left block is defined.

[@mostafaismail43]

Excellent comment! You are right. I expect users to replicate the interaction I have created in the video between the right block and the cohesive layer for the left block.

[@aliaboulatta5253]

do you mean i need to create another cohesive layer on the left block as well ??

[@mostafaismail43]

Ali Aboulatta yes

[@rakshithcr3928]

I think left block should be tied to right block's cohesive element layer??

[@reihanehjamshidi5219]

I think you are right. Have you been successful doing so? @@rakshithcr3928

In your model, you defined the cohesive elements on block 1. But how do you define the connection between the cohesive elements and block2? Or how Abaqus understands that the Cohesive element is actually kind of a glue between Block1 and Block2? It seems that something is missing from this model.

[@nicologrilli9931]

I have the same observation. I try this procedure and block 1 and block 2 are not connected at all. Only block 2 moves, where displacement boundary conditions are applied but there is no interaction. Indeed block 1 does not show any stress or displacement in the video. Creating cohesive elements require to specify that a given cohesive element includes nodes belonging to the two parts. I don't know how to do it in CAE.

He forgot to add interaction. Simply using a tie between the cohesive element and surface of the other block will do the job.

[@aquibansari5080]

@@mehdishishehbor5945 Is a 'tie' between block 1 and cohesive surface already implied when you the the mesh that way?

[@阿姆斯特朗回旋加-p5i]

​@@aquibansari5080 No, the nodes are naturally connected in block 1 and the cohesive surface, because the generation process is "offset" based on the original mesh. It's the block 2 that needs the “tie” to establish the connection.

Thank you for this video! That's really a good help for me !!

[@tinyqq8678]

Thank you for this video. Your tutorial is so clear.

[@zainsaeed147]

May i know from where we can get the properties of the cohesive material ???

[@feinonggao4677]

how can we define the interactions between the two blocks? I think simply generate another layer will not do

[@mustafakhalil007]

Hello Mr Mostafa Ismail, thank you for all your demo. they way of cohesive is very interesting , is that possible to applied that module for fiber pull-out from composite matrix ?

[@laurenciusnugroho4219]

Hello Mr. Mostafa, Can I get the detail about cohesive material property ?

[@sandyyansiku8440]

Please show the behavior of the cohesive element in terms of stress, friction or slip magnitude, etc.

[@amrmasoud5580]

Please tell me how to adjust the dynamic explicit parameters in ABAQUS to be equivalent to the static loading? Thanks

[@DolfocarAli]

thank you for the video i have question can you help me how to show the cracking area in abaqus ?

[@yura13berlin]

Thanks very much for professional lesson !!!

[@yasmeenabdelkareem477]

hello, is there any difference between cohesive elements and interface elements, or they are similar??

[@mohamedelhatmi7403]

What are E/Enn and G/Ess and G/Ett ?

[@noamaanshaikh5702]

damage initiation values

[@joeyliu8576]

why did you set the value of "out of plane" when you edited the cohesive section?

[@ceminan7927]

thank you so much for the video.

[@tawfee23okasha]

SA Mostafa I have a question. When you created the cohesive elements from the surface you assigned 0.0 thickness to it. Yet, when you defined its section you chose it to be 2 mm. I dont get this. Can you kindly explain?

[@joeyliu8576]

I can't get it either, have you figured it out now?

[@sayedghalleby2522]

Without mass?

[@nicholasfantuzzi8514]

I'd be more useful to share the INP

Thank You Sir Mustafa.... I am wondering after Knowing that Your Name is Mustafa Ismail.... Lots of Respect. From Pakistan. kindly send me your mail so that I can contact you for queries..
