Finite Element analyses and tests are performed in order to verify appropriate use of material models to represent epoxy foam in FEA. Two types of material models are studied that utilize different approaches to model behavior of materials. One uses nominal stress/strain data to depict yield condition. The other uses plastic stress/strain data and von Mises type yield condition. Due to the particular and different behaviors of epoxy foam in compressive and tensile testing, material curves in both compression and tension areas are utilized. After validation of the material model in both compressive and tensile testing, three point bending tests and simulation of foam and composite beams are carried out. Simulations of material failure and interface effects are also discussed.
