Topics in Mechanical Properties of Solids
1
1. Elasticity and Plasticity
- Deformation: Change in shape or size of a body due to external force
- Elastic body: Regains original shape and size when deforming force is removed (e.g., rubber band, steel wire)
- Plastic body: Does not regain original shape and size after force removal (e.g., clay, putty)
2
2. Stress and Strain
- Stress is internal restoring force per unit area (intensive property)
- Strain is ratio of change in dimension to original dimension (dimensionless)
- Three types: Tensile/Compressive, Volume, and Shearing stress-strain
3
3. Hooke's Law and Elastic Modulus
- Within elastic limit, stress is directly proportional to strain
- Elastic modulus = stress/strain (slope of stress-strain curve)
- Three moduli: Young's (Y), Bulk (K), and Rigidity (η)
4
4. Stress-Strain Curve
- OA: Linear region where Hooke's law is obeyed
- A: Proportional limit - end of linear relationship
- B: Elastic limit - maximum reversible deformation
Key Concepts
Stress is the internal restoring forceWithin elastic limitY = (F/A)/(ΔL/L) = FL/AΔLK =η = (F/A)/θ = Shearing stress/Shearing
