AE2253 SOLID MECHANICS |
BASICS AND AXIAL LOADING |
Stress and Strain – Hooke's Law – Elastic constants and their relationship– Statically determinate cases - statically indeterminate cases –composite bar. Thermal Stresses – stresses due to freely falling weight. |
STRESSES IN BEAMS |
Shear force and bending moment diagrams for simply supported and cantilever beams-Bending stresses in straight beams-Shear stresses in bending of beams with rectangular, I & T etc cross sections-beams of uniform strength |
DEFLECTION OF BEAMS |
Double integration method – McCauley's method - Area moment method – Conjugate beam method-Principle of super position-Castigliano's theorem and its apllication |
TORSION |
Torsion of circular shafts - shear stresses and twist in solid and hollow circular shafts – closely coiled helical springs. |
BI AXIAL STRESSES |
Stresses in thin circular cylinder and spherical shell under internal pressure – volumetric Strain. Combined loading – Principal Stresses and maximum Shear Stresses - Analytical and Graphical methods. |
