Now I want to add a material nonlinearity for my FRP composite structure....nI want to know whether material nonlinearity exists in FRP composite structures. If exists, which available material nonlinearity model in Ansys is suitable for FRP composite structures.nWhat are orthotopic stress and strain limits? why we need to include these properties in the structural analysis of FRP composite structures.nFinally, what is the significance of material nonlinearity in isotropic and composite materials?nThanks in advancenregardsnvenugopalbnn
