Stress and strain curve |
| Answer» Stress- Strain Curve :It is a curve between stress and strain. A graph is plotted between the stress (which is equal in magnitude to the applied force per unit area) and the strain produced.The graph helps us to understand how a given material deforms with increasing loads.The curve between O and A, is a straight line. This means stress is directly ∝ to strain.In this region Hooke’s Law is applicable.In this region the material behaves like an elastic body.In the region from A to B, stress and strain are not directly ∝. But still the material returns to its original dimension after the force is removed. They exhibit elastic properties. | |
