Is it possible to get ABAQUS/Explicit results (e.g. the nodal displacements) after each increments during solution?

Assume I have an explicit problem with 1 step (which itself has "n" time increments). I need the nodal results after each increments during the solution, not when the solution is completely...

I don't think so.. Constitutive laws for shell composites normally are restricted to elastic relations. Consider that interlaminar stresses normally cause failure of composites and this is not well accounted for in classical lamination theory.

Yoann Joliff

I don't know if you used the composite module present in Abaqus. But an another way is to describe the model in 2 parts : matrix and fibres. Next you can applied each constitutive law described in the software to each part.
