Does anyone know how to model a sandwich composite which has plies of WRM and CSM reinforcements ?
Abaqus has an option of defining unidirectional ply properties, but I couldn't find anything for short fiber composites or bidirectional reinforcement.
I suggest to use shell,composite section type and then define each direction with a separated ply in case your lamina is composite of two plays each play has its own direction but if your lamina is consisted of one play with fibers in two direction, I think is difficult because it will be complicated for to distinguish axis 1 from axis 2 which adopted in the fiber definition.
At the end, try to split the thickness of the lamina to the half between the two direction, otherwise u have to write your own subroutine to define this stuff.
wish u the best
