Dynamic Implicit analysis with cohesive elements

[Matheus R Silva]

It's possible to do a dynamic analysis of a composite laminated with delamination, using cohesive elements?

My objective is to analyze the frequency response function (FRF) and the natural frequencies of the laminated.

 

[GregLocock]

Yes, but no. FRF and natural frequencies apply to linear systems, so there's no particular advantage in using cohesive elements. You could do some sort of staged approach, ie do a linear analysis at distinct stages as the structure deforms, I suppose. As to the rest of your question, yes. Google.
