review text: The subject of this paper is a boundary element method (BEM) formulation and numerical implementation for inelastic axisymmetric problems in the presence of small elastic strains but large inelastic strains and rotations. A rate formulation with an elastic-viscoplastic material model, together with an updated Lagrangian description of the problem, is used in this paper. Careful attention is paid here to the analytical and numerical treatment of the complicated and sensitive kernels that arise in these integral equations for axisymmetric problems. A BEM computer program has been developed for the solution of general large strain-large rotation inelastic axisymmetric boundary/initial value problems. Numerical results for some sample problems are obtained from the BEM computer program and these results are compared against direct solutions.
