Abstract

Large quantities of nonmetallic composites such as G10-CR and G11-CR are currently under study as possible materials for magneteic fusion energy structures at low temperatures. Here we study the thermal mechanical response of cracked G10-CR glass/epoxy laminates. The composite material in generalized plane strain is assumed. Fourier transforms are used to reduce the problem to the solution of a pair of dual integral equations. The solution of the dual integral equations is expressed in terms of a Fredholm integral equation of the second kind. Numerical results on the thermal stress intensity factor and the influence of the crack on the mechanical properties at different temperatures are obtained and presented in graph form.
