Mechanics of Solids


The course deals with relationships between the external loads applied to a deformable body and the intensity of internal forces acting within the body. Topics include shafts, beams, pressure vessels, plates and shells, residual stress due to plastic deformation, strain energy, impact, Castigliano's theorem, open and closed thin walled sections, hydrostatic stress/strain, 3D Mohr circle, properties of anisotropic materials, stress function, equilibrium equations, compatibility equations, stress distribution, stress intensity factor, superposition principle, leak before burst criterion, fracture toughness test methods, energy balance principle, limitations of S-N curve and K criterion in fatigue.
