Up to a certain limit only, the stress is directly proportional to strain. … WebMar 13, 2024 · Stress-Strain Curve In a standard test to study the tensile properties of a metal a wire is stretched by the applied force. The fractional change in length (strain) and the applied force needed to cause the strain are recorded. This force is gradually increased and the change in dimensions is noted.

WebThe stress-strain curve contains no higher stress than the ultimate strength. Even though deformations can continue to increase, the stress usually decreases after the ultimate strength has been achieved. It is an intensive property; therefore its value does not depend on the size of the test specimen.
