What is a Stress-Strain Diagram?
A stress-strain diagram is a graph that represents how a part behaves under an increasing load, and is often used by engineers when selecting materials for specific designs. A stress-strain diagram generally contains three parts: • Elastic Deformation – The elastic deformation portion of the stress-strain diagram is generally represented as a linear relationship between stress and strain. If the load is released while the specimen is in the elastic deformation zone, it will return to its original dimensions. • Plastic Deformation – In the plastic deformation portion of the stress-strain diagram, the specimen begins to yield. The maximum strength of the specimen occurs in this zone, and the carried load begins to drop off as the deformation increases. The specimen endures some permanent deformation that remains after the load is released. • Rupture – The point at which a specimen breaks into two parts Stress-strain diagrams are generated experimentally through the performance of control
