[Lectures: 26 hours; Tutorials: 13 hours; Pre-requisites: NIL; Academic Unit: 3.0]
This course introduces basic concepts and principles behind material deformation, fracture, fatigue and creep. Macro-mechanical properties and microscopic analysis will be correlated whenever possible to provide insights into materials fundamentals behind the observed behaviors. The ultimate goal is to enable students to apply these principles in materials design & selection under various mechanical conditions.
Stress and strain. Elasticity and plasticity: deformation mechanisms. Strengths and failure criteria. Ductile-brittle transition. Materials strengthening. Creep deformation and failure. Fracture and fatigue.
Upon completion of the subject, the student should be able to:
- understand the mechanism of plastic deformation and origin of materials strength.
- suggest ways by which engineering materials may be intrinsically strengthened.
- derive ductile-brittle transition temperature and select materials accordingly.
- understand high temperature mechanical behavior of materials and be able to select the materials for high temperature applications.
- design and select engineering components based on the principles of fracture mechanics and fatigue.
- improve materials resistance to fracture and fatigue performance.
