Description Fundamentals of mechanics of deformable solids. Concepts of stress and strain and their relationships; Mechanics of material approach - axial forces, thin cylinders and spheres, simple (direct) shear, torsion of circular cross-section shafts; Beam bending – Euler-Bernoulli model, deflections, normal and shear stresses. Statically indeterminate problems in bending. Unsymmetrical bending problems. Combined stresses, Mohr’s circle diagram for stress and principal stresses. Theories of failure. Experimental methods of stress analysis – strain gages, strain rosettes and photoelasticity. Theory of elasticity approach - equilibrium equations, strain displacement relation, plane stress and plane strain, stresses in thick cylinders. Energy methods – Castigliano’s theorem and its applications. Potential energy methods and applications. Buckling of columns.
