MAT_054 Vs. MAT_058
I am hoping someone can discuss the fundamental differences between MAT_054 and MAT_058 composite models.
From what I have seen, MAT_058 describes a composite as nonlinear elastic whereas 54 depicts the composite as linearly elastic.
In regards to MAT 58 being a continuum damage model, and MAT 54 as a progressive ply failure, what is the main difference in these solving approaches?
Any insight is appreciated!
