Stress-Strain Curve
The stress-strain curve is a graphical representation that shows how a material deforms under stress. Stress is the force applied to a material, while strain is the resulting deformation. The curve typically has three key phases: the elastic region, where the material returns to its original shape after removing the stress; the plastic region, where permanent deformation occurs; and the fracture point, where the material breaks. This curve helps engineers and scientists understand a material's strength, flexibility, and durability, guiding decisions in construction, manufacturing, and various applications where material performance is critical.

The stress-strain curve visually represents how materials respond to stress or force. Stress measures the force applied to a material per unit area, while strain measures the resulting deformation. As stress increases, most materials initially stretch or deform elastically, returning to their original shape when the force is removed. Beyond a certain point, they may enter plastic deformation, where they permanently change shape. Eventually, if stress continues, materials can break. This curve helps engineers understand material properties and predict behavior under different loads, ensuring safety and functionality in structures and products.

The stress-strain curve is a graphical representation that shows how materials respond to applied forces. "Stress" measures the force applied to a material, while "strain" measures the material's deformation or change in shape due to that force. The curve typically starts with a linear region where the material deforms elastically, meaning it returns to its original shape once the force is removed. Beyond a certain point, the material undergoes plastic deformation, meaning it won't return to its original shape. The curve helps engineers understand material behavior, predicting when it will bend, break, or fail under different load conditions.
