I am working on Epoxy material damage for a research project. We observed from the experiments that the Epoxy material just fails without any plastic deformation and tensile strength is lower than compression strength(2-3 times). So, in order to simulate the material damage model in Abaqus, could anyone advise me that which damage model I should consider for the analysis?. In Abaqus, most of the material-damage models available for ductile materials, for example, General Ductile, Johnson-Cook, Druckker Prager model, etc..Although I could see brittle cracking model in Abaqus, its only available in Abaqus/Explicit if am not wrong..
Thanks in advance,,
