Computational Procedure for Durability Prediction of Polymers and their Composites
Abstract
An analytical tool that can be coupled with accelerated material characterization to be used for long-term durability prediction of polymeric materials and their polymeric matrix composites (PMC) is described. It employs a specialized finite element code (NOVA-3D) to solve three-dimensional stress analysis problems. A viscoplasticity functional is included to account for stress-history dependent inelastic strains. A 3D transient nonlinear Fickian diffusion model is used to model penetrant diffusion. Effect of physical aging is also included in the model by means of an effective-time parameter. A computer simulation of the transverse creep response of a unidirectional IM7/5260 composite subjected to cyclic thermo-mechanical loading is presented.
