Hello everyone,

I am new of Radioss and exploring how to simulate impact on composite.

I am looking to capture progression of delamination in composite while bullet penetrate.

Shall it be possible with brick element?

I have tried with MAT/LAW12 and  P22_TSH_COMP along with HASHIN failure. but I am unable to capture delamination. I am using Type7 contact formulation.

Also, The plate deformation increases without element deletion. however I used Idel 2 in contact definition.

Projectile velocity plot is attached here for reference.

 

Any suggestion and help is appreciated.

Thanks,

Ansari

    Hi

    You could add /FAIl/HASHIN wit Ifail_so set to have the element deletion.

    I hope this is helpful.
