A 2D time domain boundary element method(BEM)is developed to solve thetransient scattering of plane waves by a unilaterally frictionally constrained inclusion.Coulombfriction is assumed along the contact interface.The incident wave is assumed strong enough sothat localized slip and separation take place along the interface.The present problem is in effect anonlinear boundary value problem since the mixed boundary conditions involve unknown intervals(slip,separation and stick regions).In order to determine the unknown intervals,an iterativetechnique is developed.As an example,we consider the scattering of a circular cylinder embeddedin an infinite solid.
