Mechanics of Solids

This module develops the principles of stress and strain in three dimensions and illustrates the 2D plane stress and plane strain states as special cases of the 3D scenario. Stress and strain transformations in 3D and 2D are studied and special stresses and strains such as principal stresses and strains in 3D etc. are discussed. Equilibrium, compatibility and constitutive relationships are developed. Practical stress analysis scenarios such as in members undergoing combined bending and torsion and in pressure vessels. Particular attention is given to fracture mechanics and fatigue life assessment.
