Multi-scale modeling of high-temperature polymer matrix composites for aerospace applications

S. Roy     University of Alabama, Tuscaloosa, AL, USA

Abstract

In this chapter, a novel numerical–experimental methodology is outlined to predict delamination in pristine as well as isothermally aged (in air) polymer matrix composites. A rate-dependent viscoelastic cohesive layer model was implemented in an in-house test-bed finite element analysis (FEA) code to simulate the delamination initiation and propagation in unidirectional polymer composites before and after aging. This unified multi-scale model is fully rate-dependent and does not require a preassigned traction–separation law. The actual shape of traction–separation law depends on (1) the strain ...
