| DESCRIPTION | Syllabus - Elasticity Types of stresses. Stress at a point and on an oblique plane - direct, shear and resultant stresses. Principles stresses and strains in 3 dimensional - Mohr's circle representation. Graphical representation of the state of the stress at a point and on a general plane. Stress equations of equilibrium. Stress-strain relationships. Applications of the stress function concept to various engineering problems. Plasticity. Plastic behaviour of solids - dislocation dynamics, influence of strain rate and temperature. Effects of defects and work hardening, mechanisms of slip. Textures in materials. - Plasticity - plastic bending of rectangular sections, shape factor symmetrical sections, partially plastic bending of unsymmetrical sections. Torsion of strained shafts, plastic torsion of tubes, plastic bending and torsion of case hardened materials. - Fracture Mechanics Fundamentals of fracture - ductile and brittle fracture. Principles of fracture mechanics - stress concentration, stress analysis of cracks, fracture toughness, design using fracture mechanics. Impact fracture toughness, fatigue fracture, and creep.
