Dear Biswal,

There is one module called "interaction", if you are using abaqus. There you can input the interaction properties you want. I think for your case while assigning constraints "embedded region" would be the right choice to go on with. 

But, still if its possible, be specific about your problem, so that I can guide you in detail.

Regards,

Hi

May I please ask you how you modeled randomly distributed CNT reinforced composite?

I have modeled in CNT reinforced composite in MATLAB  and using COMSOL MATLAB live link imported it to COMSOL.I am attaching the document for your consideration which i had followed .

Its easy to model RVE using Digimat from Nastran (For randomly oriented short fiber reinforced composite)

You can define cohesive surface or cohesive elements to model the fiber matrix bond in ABAQUS. To define cohesive surfaces, you do not need to define any parts, you can simply select the surfaces in contact. 

Hi all

please i need to know how i can distribute fibers in random pattern using abaqus

How do you set particles randomly?

I am new to MATLAB but I want to generate random locations of 15 particles at specified distances in a given 3D space. Can you help me in doing this?

Hi

you can use RSA algorithm

If you are still interested on generating randomly distributed cylindrical particles please have a look at this journal paper. I described the algorithm step by step in this paper which enables manipulating the orientation of the particles as well. Basically, with this method you can create a randomly dispersed and oriented cylindrical particles.

Thanks,
