I have results for dynamic strength of resin at a higher strain rate. I want to use these results to evaluate material properties of CFRP at the higher strain rate assuming fiber strength isn't affected significantly by higher strain rate. I want to use this model of impact loading test using a macro-scale model (Fibre and Resin are not separate) hence I can't use the Cowper-Symonds model. Also, how to implement this model for impact loading simulation? If using meso-scale simulation is one of the option what is the procedure that can be followed?
