GITAM University Mechanics of Solids Syllabus

 UNIT-I:
Effects of force: tension, compression and shear. Stress as internally elastic resistance of a material
– strain – property of elasticity – Hooke’s law – stress-strain diagrams. Lateral strain, Poisson’s
ratio. Complementary Shear Stress, Shear Strain, Shear Modulus. Relation between Modulus of
Elasticity, Modulus of Rigidity and Bulk Modulus. Stresses in Composite Assemblies due to Axial
Load.
