Introduction to Theory of Elasticity: Stress tensor, plane stress and plane strain problems and formulation of stress function.
Theory of Yielding/Failure (Plastic Limit Analysis):  for ductile and brittle materials.
Cylinders: Thin, Thick and Compound Cylinders
Column: Stability of columns, conditions of equilibrium, eccentrically loaded columns, initially imperfect columns.
Flat Plates: Introduction, Stress Resultants in a flat plate, strain displacement Relations, Stress-strain-temperature relation of isotropic elastic plates, Strain Energy of plate, Solution of rectangular and circular problems Bending and Buckling of plates.
Curved Beams: Introduction to circumferential and radial stresses in curved beams, Correction of Circumferential Stress in curved beams having I, T-cross section, Unsymmetrical bending, Deflection of curved beams.
Torsion of Thin Walled Tubes and Non-Circular Members: Saint Venant’s semi inverse method, Prandtel’s Elastic Membrane Analogy, Narrow Rectangular Cross-section, Hollow Thin Walled Torsion Members.
