Energy Approach to Sub-Grain Formation
Original language description
Variational formulation of the incrementally linear rigid-plastic approximation to crystal plasticity is set up. It is shown that the subgrain formation is a consequence of a tendency to minimize the sum of the incremental dissipated energy and the incremental energy that is related to the increase of flow stress. A physically motivated nonlocal formulation of the variational problem leads to a finite size of the subgrains formed. A crystal deformed by symmetric double slip is considered as an example

Energetický popis tvorby subzrn
Czech description
V rámci variační formulace přírůstkové tuho-plasticity je ukázáno, že tvorba subzrn je důsledkem tendence minimalizovat součet disipované energii a změny vnitřní energie vyvolaný vzrůstem skluzového napětí. Fyzikálně motivovaná nelokální formulace variačního problému vede ke konečné velikosti tvořících se subzrn
