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.
