摘要：

A parametric variational principle, the parametric minimum potential energyprinciple (abbreviated to PMPEP), is presented for the elastoplastic problems. The principle proposedis free from the restraint of Drucker’s postulate and consequently suitable for solving thenonassociated plastic flow problems in rock, soil, concrete and other geomaterials.
