Syllabus

Fundamentals of fracture mechanics: Griffith’s crack theory, Strain energy release rate, Stress analysis of cracks and linear elastic fracture mechanics (LEFM), Crack tip plastic zone, Plane strain and plane stress fracture toughness, Plane strain fracture toughness determination, Plane stress fracture toughness determination, Fracture toughness determination using J-integral approach.

Non-destructive testing of defects: visual inspection, liquid penetration inspection, magnetic particle inspection, eddy current inspection, ultrasonic testing, radiographic inspection.
Phenomenological description of various modes of failure, fracture, fractography

Different failures: Fatigue failure, creep and stress rupture failures, environment-assisted failures, wear failures, common failures in castings, weldments, gears, shafts and springs, failures of composites

Analyses of engineering failures: Typical defects, macroscopic fracture surface examination, metallographic and fractographic examination, steps in failure analysis, case histories.

Understanding different engineering failures

1. Development of skills about fracture mechanics
2. Development of knowledge-base to understand different engineering failures
3. Generation of the skills about different non-destructive test methods and their implementation
4. Learning of methods to detect/estimate the cracks/flaws those are present in materials
5. Development of knowledge-base to understand the reasons behind various mechanical failures through structure-property correlations.
6. Development of understanding about different case studies from recent reports on failure analysis
