Course Content (Syllabus)
Failure Analysis Methodology: Failure mechanisms. Causes of failure and breakdowns. Methods for failure investigation. Fracture phenomena. Linear fracture mechanics — Griffith theory and failure criteria. The concept of stress intensity factors. The concept of the critical stress intensity factor. Determination of critical crack length and critical failure load. Tests for assessing mechanical property failures. Failures due to fatigue, wear, mechanical corrosion, friction, corrosion, high temperatures. Fracture surface morphology: detailed presentation of fracture mechanisms. Case study presentations of failures.
Materials Design and Selection: Criteria for material selection, requirements of mechanical design, materials selection charts, material performance indices, multiple objectives and constraints, selection of materials and cross-sectional shapes. Examples of material selection to minimize cost and weight. Energy and environmental criteria in material selection.
