Abstract

A procedure for analyzing moire fringe patterns using boundary elements is presented. The kernels of the boundary integrals are based on anisotropic elastic Green's functions developed for bimaterial problems. The numerical procedure is shown to be a logical extension of the local collocation method developed for linear elastic fracture mechanics. A numerical example is given for purposes of investigating the convergence of the solution to the linear least squares problem. Examples of the use of three different types of Green's functions are also given for different conditions on the bimaterial interface. Introduction The reliability of interfaces play a key role in the performance of composite materials, electronic packaging structures, thin films, and adhesive joints. This paper will focus on one method of analyzing exp
