Course objectives: |
systematic presentation of the elements of failure analysis and structural integrity; introduction to dimensions of life-time management; overview of basic concepts of fracture mechanics and their characteristics; application of fracture mechanics in structural safety |
Course content and structure: |
Failure modes and statistics, loading modes and types, connection among loading and failure modes. General scheme of failure analysis. Conceptual model of structural integrity: global, experimental and information-technical aspects. Dimensions of life-time management. Classical and fracture mechanical design philosophies. Low cycle fatigue, high cycle fatigue, fatigue design curves. Basic concepts of fracture mechanics: linear elastic, elastic-plastic and dynamic fracture mechanics; environmental and velocity influences. Fracture toughness values, fatigue crack growth, crack opening displacement, R-curves. Application of fracture mechanical concepts in safety of different structures, case studies. |
Evaluation method: |
written and oral exam at the end of semester |
