Elastodynamic Response of an Orthotropic Strip with Two Coplanar Cracks

Abstract

The elastodynamic response of two coplanar finite cracks in an infinite orthotropic strip due to longitudinal waves incident normally on the cracks has been investigated in this paper. Fourier transforms are used to reduce the mixed boundary value problem to Cauchy‐type singular integral equation, which is solved numerically. The stress intensity factors at the edges of the cracks have been derived and plotted against dimensionless frequency for different geometry parameters. Also normal stress out side the cracks has been calculated numerically and plotted for different parameters and different materials.
