If the true stress, based on the actual cross sectional area of the specimen, is used, it is found that the stress strain curve increases continuously up to fracture. If the strain measurement is also based on instantaneous measurements, the curve, which is obtained, is known as a true stress true strain curve. This is also known as a flow curve since it represents the basic plastic flow characteristics of

## Stress Strain CurveWhat Exactly Is The Stress Strain Curve?

May 13, 2016 · Thus, there are two stress strain curves, one that describes ductile materials and another that describes brittle materials. Lets first consider the former. Ductile Curve. When a ductile material, such as copper or aluminum, is put under stress, initially, the resulting strain is proportional to the magnitude of the forces.

## Stress strain Diagram Strength of Materials Review

This may be calculated as the area under the entire stress strain curve (from O to R). The toughness of a material is its ability to absorb energy without causing it to break. Working Stress, Allowable Stress, and Factor of Safety Working stress is defined as the actual stress of a material under a given loading.
