I want to model a combined viscoelastic (VE)-viscoplastic (VP) analysis for Fiber Reinforced Polymer (FRP) composites subject to simultaneous mechanical load and conduction of heat. I know fibers should be considered as linearly elastic with regards to their mechanical response. I have no idea about FE Material model! Can anybody help?
Dear Mohammad Reza Bayat,
To get the material model of FRP material for your simulation, you can use Digimat material model. To extract the Digimat material model you need to have the mold flow model as input for Digimat. Digimat will consider the fiber orientaion effect in matrix of the material.
Dear Mohammad:
My main experience is on Abaqus and Ls-Dyna; so I do not know what options do you have in Ansys. Basically material model ar build up under usermat subroutines, but there are other easier options (as in Abaqus). The need will depend on how complex your material model is (internal variables, coupled problems, etc).
Dear Mohammad
You can try in Radioss it give much flexibilty for composite modelling
