Summary:This paper deals with the elastoplastic boundary element formulation applied to transient problems. An improved procedure to take into account the non-linear influences on acceleration and velocity is proposed. Integral representations of displacements and strains are derived taking into account the following domain terms: plastic strains, mass effects, viscosity and other temperature-like effects. The required domain variable approximations are given by adopting internal cells over which shape functions are properly defined. The Kelvin static fundamental solution is used in writing the integral representations, which gives the matrix time dependent differential equation that governs the problem.
