DETERMINATION OF STRESS INTENSITY FACTORS IN AN ORTHOTROPIC STRIP WEAKENED BY TWO CRACKS

Abstract

In this paper, stress intensity factors (SIFs) at the edges of the cracks in an elastic orthotropic strip weakened by two collinear cracks are determined. The problem consisted of two symmetrical cracks about the sides of the strip and axis y- is approached by Iterative method. Also, by reducing the problem to a system of Cauchy type singular integral equations, a Quadrature technique is used to calculate SIFs. Finally, extensive numerical results and detailed interpretations are given.
