Anotace
The main objective of the project is the accuracy improvement of a numerical prediction for a reliable fatigue life estimation and of the complete description of the composite and metallic materials behavior. Partial aims are following:
- The application of advanced statistical description for fatigue curves of silicon based composites.
- To suggested a procedure using thermographic techniques together with advanced probabilistic models for description of metallic material fatigue behaviour as a quick and economical tool for obtaining the fatigue limit.
- Experimental results will be used as input data for numerical calculations of the fatigue predictions.
