✦ Synopsis

With

the application to weld defects in mind, the interaction problem between a planar crack and a flat inclusion in an elastic solid is considered. The elastic inclusion is assumed to be sufficiently thin so that the thickness distribution of the stresses in the inclusion may be neglected. The problem is reduced to a system of four integral equations having Cauchy-type dominant kernels. The stress-intensity factors are calculated and tabulated for various crackinclusion geometries and the inclusion to matrix modulus ratios, and for general homogeneous loading conditions away from the crack-inclusion region.

One of the key requirements for developing tough multiphase blend systems, for example, selecting the type of discrete phases (hard or soft) in a polymer matrix, is the ability to predict the fracture path. Most of these selections rely heavily on prior experience or on intuitive rationale. There ar

The problem of the scattering of time-harmonic elastic waves by a configuration of a crack and an adjacent inclusion embedded in a 2-D infinite elastic medium is investigated by the traction boundary integral equation (TBIE) method. The result of the formulation is a system of six coupled singular i
