s--Some results of high speed interferometric measurements on dynamically propagating interfacial cracks are presented. Polymethylmethacrylate (PMMA)/steel bimaterial specimens of the one-point bend type are used. They are impact loaded using either a drop weight tower device or a high speed gas gun. This results in two distinct groups of experiments at different loading rates. In all cases ver...

An experimental investigation dealing with failure characterization of 63/37 soldercopper interfaces is presented. The method of moird interferometry is used for mapping elasto-plastic deformations in bimaterials subjected to predominantly tensile loading. A method for quantifying the fracture parameter--the J-integral--using full-field measurement of crack opening displacements has been develo...

A closed-form solution is obtained for the problem of a mode-III interfacial edge crack between two bonded semi-infinite dissimilar elastic strips. A general out-of-plane displacement potential for the crack interacting with a screw dislocation or a line force is constructed using conformal mapping technique and existing dislocation solutions. Based on this displacement potential, the stress in...
