Název v původním jazyce

Identification and Integration of Directional Distortional Hardening Model in Case of Monotonic Proportional Loading

Popis výsledku v původním jazyce

Plastic straining of metals can induce distortion of yield surface. This phenomenon is referred to as the directional distortional hardening and was modelled by several authors. A comprehensive model of directional distortional hardening is presented andsome properties of the model are emphasized. It is shown that model can be analytically integrated and this integration is used for identification of model. There are developed two identification algorithms that are suitable for both the monotonic and cyclic loading. Existence of solution for these algorithms is guaranteed. Finally, some identification examples are presented.
