A Computationla Procedure for Durability Prediction of Polymers and Their Composites

摘要

The purpose of this paper is to describe an analytical tool, which, when coupled with accelerated mateiral characterization, is capable of predicting long-term durability of polymeric materials and their composites. The analytical tool cosists of a specialized finite element code (NOVA-3D) that can be used for the solution of three-dimensional stress-analysis problems with large displacements and rotations. Some of the modeling attributes necessary for durability prediction of polyments and polymer matrix composites (PMC) are discussed below.
