Module content

Concept of Stress: Stresses in structural members, stress on oblique plane and stress under general loading, components of stress, design considerations. Stress and Strain: statically indeterminate problems, thermal effects, Poisson’s ratio, generalised Hookes Law, shearing strain, stress-strain relationships. Torsion: Torsion of circular bars, stresses and strains in pure shear, power transmission, and statically indeterminate torsional members. Pure Bending: symmetric members in pure bending, stresses and deformations, deformations in transverse cross-sections, members made of composite materials, eccentric axial loading. Analysis and Design of Beams for Bending: shear and bending moment diagrams, relationships between load, shear and bending moments, design of prismatic beams for bending. Shearing stresses in Beams and Thin-Walled Members: Horizontal shearing stresses in beams, shearing stresses in Thin-Walled members. Transformation of Stress and Strain: Plane stress transformation, Mohr’s circle, principal stresses, maximum values and stress variation in prismatic beams; Plane strain transformation, Mohr’s circle, principal strains, maximum values, general state of stress, stresses in Thin-Walled pressure vessels. Principal Stresses under a given Loading: Principal stresses in beams, design of transmission shafts, stresses under combined loads. Deflection of Beams: Deformation under transverse loading, statically indeterminate beams, method of superposition. Energy Methods: Strain energy, elastic strain energy, strain energy for a general state of stress.
