Abstract

In this paper, the two dimensional interaction of p-waves with an edge crack in an infinite orthotropic strip has been studied. The mixed boundary value problem of determining the unknown stress distribution outside the crack has been converted to the determination of the solution of a Fredholm integral equation of second kind by Fourier transform. Stress intensity factor (SIF) at the tip of the crack has been calculated by solving integral equation numerically and plotted to show the effect of strip width on SIF. Finally normal stress at distant points from the crack has been calculated and plotted for various parameter to show the effect of material orthotropy.
