Abstract

Controlling damage progression in oxidative environments is critical for enhancing the long-term durability of polymeric resins and composites. Elevated temperatures and pressures accelerate oxidation and damage growth rates. A threedimensional finite element method is used to simulate both oxidation layer and damage growth under uniaxial tension. As the simulations have considerable computational burden due to the numerous degrees of freedom at each node, a parallel solver that utilizes multiple processor cores is employed to reduce the wall clock time required for the simulations. This paper describes the damage growth behavior of a compact tension specimen under tensile loading in oxidative environments. A stress-based propagation criterion with higher failure strength for the un-oxidized matrix and lower strength for oxidized resin is used.
