Inelastic Deformation and Failure Analysis of Filament-Wound Composite Structures

Abstract

This report summarizes the results of investigation during the initial phase of the project. Much of the effort in this period was expended in two areas. First, the existing literature on theoretical and experimental studies of the response, strength and failure behavior of filament-wound tubes was examined and studied. Secondly, a tentative analytical approach was conceived on the basis of available experimental results. The immediate objective of this analytical approach is to describe, in a qualitative manner, the dominant effects associated with the occurrence of the expansion mode and the shear mode of failure, and to provide a mathematical model for the small-strain inelastic deformation accompanying the initiation of such failures. Keywords: Inelastic deformation, Failure analysis, Composite structures, Filament-wound tubes.
