Progress in Applications of BEM to Inelastic Analysis of Solids
A number of recently developed boundary element solutions are used for solving a range of elastoplastic and thermoplastic problems. The first algorithm is the conventional volume integral formulation in which the unknown boundary solution and the initial stress (or strain) rates are found together either in an incremental iterative fashion or by a direct variable stiffness type algorithm. The second procedure which is entirely new differs from the previous one in that volume integration is not required to incorporate the nonlinear effects in the analysis. Instead, initial stress rates are introduced in the boundary element system via particular integrals.
