Optimización Aplicada a la Formulación y Solución del Modelo Cinemático para Elasto Plasticidad

Mildred Ballin Hecke, Néstor Zouain Pereira, Lavinia Alves Borges, Raúl A. Feijóo


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.
