Research output: Contribution to journalArticlepeer-review


The elastodynamic response of a single-edge crack in a semi-infinite orthotropic medium is considered in this study. The crack is oriented in a direction normal to the edge of the half-plane. 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 to the dual integral equations is then expressed in terms of a Fredholm integral equation of the second kind. Numerical values on the dynamic stress intensity factor for some fiber-reinforced composite materials are obtained and the results are graphed to display the influence of the material orthotropy.
