Closed-form solutions for a mode-III moving interface crack at the interface of two bonded dissimilar orthotropic elastic layers
Summary: An integral transform technique is used to solve the elastodynamic problem of a crack of fixed length propagating at a constant speed at the interface of two bonded dissimilar orthotropic layers of equal thicknesses. Two cases of practical importance are investigated. Firstly, the lateral boundaries of the layers are clamped and displaced in equal and opposite directions to produce antiplane shear resulting in a tearing motion along the leading edge of the crack; and secondly, the lateral boundaries of the layers are subjected to shear stresses. An analytic solution for a semi-infinite crack at the interface of two bonded dissimilar orthotropic layers has been derived. Closed-form expressions are obtained in all cases for stress intensity factors and other physical quantities.
