摘要: Abstract The elastoplastic boundary value problem in terms of rates, formulated using integral equations linear elasticity, is shown to be amenable, through discretizations, a complementarity endowed with symmetric matrix (in contrast the traditional element formulation). This symmetrization achieved by suitably choosing fundamental solutions and formulating for quantities stresses, enforcing Galerkin weighted-residual sense (instead collocation) plastic constitutive laws over domain cells.
