Elasticity is a property of a body by virtue of which it returns to its original shape and size when the deformed forces are removed. Under some load conditions, a body experiences an elastic deformation, which can be studied using stress and strain curves. The stress-strain curve is divided into five points: proportional limit, elastic limit, yield point, ultimate stress point, and fracture point. The initial region of the curve where the stress is directly proportional to the strain and obeys Hooke'’ Law is known as the proportional limit. The elastic recovery of a body is possible when the applied force and the associated deformation are within the limit, known as the elastic limit. During elastic deformation, atoms of the body are displaced from their site and return to their original position once the applied forces are removed. It also marks the end of elastic behavior and the beginning of plastic behavior of such bodies.
