Summary

The lecture introduces students to the basics of modeling stress deformation and fracture behavior of structural materials. Microstructural models of material damage and application of local approach methods are the basis for predicting time the limit state of plastic deformation, brittle unstable quarries creep, low cycle fatigue and vysokocyklové. Related reading numerical solution methods and examples of the behavior of selected types of components when exposed to these processes, illustrative of damage depending on the time and load design shows the evolution of these processes and allows estimation of the moment of limit state design. Knowledge of numerical models of damage are the basis for their design simulations in selected structures construction materials for typical uses. At the end of lectures are presented some selected technical applications process modeling damage for different variants of the choice of material intended for the production of one and the same components.
