Laminate Analyses, Micromechanical Creep Response, and Fatigue Behavior of Polymer Matrix Composite Materials.

Abstract

Three major topics were pursued. The two-dimensional fintie element micromechanics analysis was extended to include nonlinear viscoelastic material response. Analytical predictions of the time-dependent behavior or both glass/epoxy and graphite/epoxy unidirectinal composites subjected to transverse compression were then correlated with experimental data also generated as part of this study. The viscoelastic properties of the epoxy matrix were also determined, as required input to the analysis. A new three-dimensional finite element analysis was developed, incorporating inelastic orthotropic material response, temperature- and moisture-dependent material properties, and improved numerical solution techniques. This analysis is permitting the study of both micromechanical and laminate problems.
