Distortion

Distortion means change of shape. When a body is subjected to stress it undergoes a change of shape and is said to become distorted or strained. Strictly speaking, strain applies to any change in the dimensions of the body, whereas distortion applies to irregular change. A sphere compressed to a smaller sphere is strained but not distorted; a. sphere compressed to an ellipsoid is distorted.
