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.
Learning Outcomes of the Course Unit
- Clarify methods of components material damage in operational conditions;
- Outline material damage mechanisms by mechanical and deformation origin of cyclic loading and by environment influence;
- Outline fundamental elements of the long time management system of components operation;
- Explain of corrosive environment influence on fatigue of materials;
- Compare approach of mathematical modeling of material damage with non-destructive or destructive testing approach;
- Apply probability approach on determination of material damage level and trends;
- Design of diagnostic system for running up-to-date of the level and trends of material damage in operational conditions;
- Assess the results received by diagnostic system from point of view asked reliability of structures.
