The extent to which a body is distorted when it is subjected to a deforming force, as when under stress. The distortion can involve a change both in shape and in size. All measures of strain are dimensionless (they have no unit of measure). ◇ Axial strain is equal to the ratio between the change in length of an object and its original length. ◇ Volume strain is equal to the ratio between the change in volume of an object and its original volume. It is also called bulk strain. ◇ Shear strain is equal to the ratio between the amount by which an object is skewed and its length. Compare stress. See more at Hooke’s law.
