Abstract:The conception of non-coupled systems is intro-duced and the variational principles of physical simulationwere established in auither's papers. Anti-coupled systems andequations of spring back are given, and potential energy prin-ciple, complementary energy principle, generalized potentialenergy principle and generalized complementary energy prin-ciple of spring back for physical simulation are established inthis paper on the basis of the conception and principles of the-anther's papers. Meanwhile, the potential energy principle ofspring back for physical simulation is applied to spring backcalculation of an elastoplastic thick wall cylinder.
Keywords:physical simulation  spring back  variational principle  generalized variational principle
