A spectral formulation of the boundary integral equation method for antiplane problems is presented. The relates slip and shear stress at an interface between two half-planes. It involves evaluating a space-time convolution or interface. In formulation, with respect to spatial coordinate performed in domain. This leads greater numerical efficiency. Prior work on has elastodynamic present work, ...

A surface integral equation (SIE) method is developed to analyze electromagnetic scattering by 3-D objects with soft-and-hard/DB (SHDB) boundary conditions. The SHDB condition a generalization of the soft-and-hard (SH) and DB conditions that associate normal tangential field components on boundary. In method, expressed in vector form allows combining it equations. obtained equations can be disc...

in this article, a transversely isotropic linear elastic half-space with depth wise isotropy axis of material containing a cylindrical cavity of finite length is considered to be under the effect of an arbitrary torsion force applied on the wall of the cavity. to this end, the equation of equilibrium has been written in a cylindrical coordinate system, by dividing the involved domain to two reg...
