摘要:A variational formulation for the elastic-plastic analysis in terms of finite increments of di.placements and plastic multipliers is derived from a minimum principle for velocities and rates of plastic multipliers, by using optimization concepts. We discuss some alternative proceelures for the solution of the discretized problem, using several mathematical programming techniques.
