Two Elastic Half-Planes Bonded Through an Elastic Layer Weakened by Two Identical Interface Cracks : Solid-Mechanics, Strength of Materials

Abstract

Stresses around two symmetrically located interface cracks which lie in the composite materials constructed of two elastic half-planes bonded through an elastic layer are examined. To avoid the oscillatory stress singularities near the crack tips, the crack surface displacements are expanded in trigonometrical functions accompanied with the unknown coefficients. A modified version of the Schmidt method is used to determine these coefficients. Numerical calculations are carried out for the stress intensity factors.
