Abstract

Abstract-This paper considers the impact response of G-10CR glass-epoxy laminates with a crack at low temperatures. Laplace and Fourier transforms are used to reduce the transient problem to the solution of a pair of dual integral equations in the Laplace transform plane. The solution of the dual integral equations is then expressed in terms of a Fredholm integral equation of the second kind. A numerical Laplace inversion routine is used to recover the time dependence of the solution. Numerical results on the dynamic stress intensity factor at low temperatures are obtained and are presented in a graphical form.
