ME201: MECHANICS OF SOLIDS
MODULE I

Introduction to analysis of deformable bodies – internal forces – method of sections – assumptions and limitations. Stress – stresses due to normal, shear and bearing loads – strength design of simple members. Definition of linear and shear strains.

Material behavior – uniaxial tension test – stress-strain diagrams concepts of orthotropy, anisotropy and inelastic behavior – Hooke’s law for linearly elastic isotropic material under axial and shear deformation.

Deformation in axially loaded bars – thermal effects – statically indeterminate problems – principle of superposition – elastic strain energy for uniaxial stress.

MODULE II

Definition of stress and strain at a point (introduction to stress and strain tensors and its components only) – Poisson’s ratio – biaxial and triaxial deformations – Bulk modulus – Relations between elastic

Torsion: Shafts – torsion theory of elastic circular bars – assumptions and limitations – polar modulus – torsional rigidity – economic cross-sections – statically indeterminate problems – shaft design for torsional load.

FIRST INTERNAL EXAM

MODULE III

Beams- classification – diagrammatic conventions for supports and loading – axial force, shear force and bending moment in a beam

Shear force and bending moment diagrams by direct approach
