Hi everyone,
I am a new Abaqus user and I am trying to create a high velocity crushing simulation of a composite tube. I have to use COHESIVE elements to simulate cohesion bonding, inter and intra damage propagation.
I have some questions I hope someone could kindly help me to answer:
1) Should I use a shell or solid composite layup/section for this kind os simulation?
2) How should I introduce cohesive elements inside my layup to simulate interlaminar damage propagation (matrix failure)? should I create a "decohesion material" (like epoxy resin) and introduce it in my layup with a very small thickness?
3) How can I assign COHESIVE elements to a specific ply inside a composite layup?
I hope someone can give me a little help. Thank you in advance!
Best regards,
