Abstract : Various plasticity theories are discussed as models for the behavior of real materials. The simple rigid/perfectly plastic model is shown to be a reasonable first approximation. Once the theory for this model has been developed it is easily modified to account for strain-hardening and elastic effects. It is shown in various examples that for loads less than the rigid/perfectly-plastic limit load strain-hardening has a negligible effect, whereas for greater loads elastic strains can reasonably be neglected.
