coefficient of strain

[¦kō·ə′fish·ənt əv ′strān]

(mathematics)

Multiplier used in transformations to elongate or compress configurations in a direction parallel to an axis.

(mechanics)

For a substance undergoing a one-dimensional strain, the ratio of the distance along the strain axis between two points in the body, to the distance between the same points when the body is undeformed.
