Hi, I was trying to introduce the mechanical properties for a composite component made of CFRP (Composite Fibre Reinforced Polymer). As I'm a beginner, I'm following the book Practical Aspects of Finite Element Simulation by Altair University. In there, I've found mechanical properties for many other materials, as I show in the image, but I can't find some general properties to define CFRP. Moreover, as it is an orthotropic material, I've learnt from the tutorials that I need to specify more data. Can anyone help me to find the general properties I need in the picture for MAT8 in order to define CFRP material? If possible, I'd like to see the reference for checking it up. Thanks in advance, Julio
I ran a simulation with a non linear material ( Having a stress strain curve data upto its ultimate tensile stress). In the simulation results, the von mises stress exceeds the limit of stress I have entered in the curve data. What is happening here? Is the software extrapolating from the data OR assuming zero resistance from the regions where the von mises stress has exceeded the ultimate limit.
