This study introduces a novel numerical procedure for conducting shakedown analysis on structures subjected to cyclic loads. The determination of safety load multipliers is achieved through the integration edgebased smoothed finite element method (ESFEM) and conic programming. By applying smoothing technique, all constraints are satisfied in an average manner within domains, as opposed at numerous Gauss points Finite Element Method (FEM). approach results reduction problem size number variables. formulated optimization associated with standard form second-order cone programming (SOCP) addressed using highly efficient solvers. A series benchmark examples examined demonstrate computational efficacy proposed method.
