Reply To: Crystallinity of fiber composites

[tslavik]

We are not in a position to say which of the composite material models would best suit your particular application.To get a feel for models available in LS-DYNA, please see MATERIAL MODEL REFERENCE TABLES at the beginning of the *MAT section of the "Vol II Materials" manual, and look for models with a CM in the APPS columnUnfortunately, LSTC cannot provide specific material data or specific advice on how to obtain such data experimentally.
Give it a try, bu It seems there are no models that meet that requirement.Also, please search the Vol II user's manual for the word "crystal" and you'll see there are few models which handle that level of detail.You might also searchwww.dynalook.comfor the same.And, a search for "crystallinity" identifies only the paper below.It seems like users interested in this area have resorted to programming their own user-defined material model.
