• 520 __ |a To understand and quantify debonding events in composite materials it is necessary to have accurate stress analysis in the area of stress concentrators. Boundary integral equation (BIE) techniques are proposed as a potentially more accurate approach than finite elements. In particular, the debond stress analysis of a rod being pulled out of a matrix material is considered. A model problem is posed consisting of an edge cracked bar under longitudinal shear deformation and a BIE formulation is proposed using a subtraction of singularity technique. An extensive review of integral equation approaches to various fracture mechanics problems is also presented, with suggested new solution techniques for unsymmetric crack configurations. Originator-supplied keywords include: Boundary integral equations, Boundary elements, Boundary element methods, Fracture mechanics, Stress singularities.
