Less common ways of formulating this tensor-field quantity include one named after either Euler or Almansi which references the system's final configuration. The Green-Lagrangian tensor of this quantity is equal to one-half the difference of the Cauchy-Green deformation tensor and the identity, a formulation equal to one-half the difference of the product of the deformation gradient times its transpose and the identity. A yield surface maps out the values of this beyond which a material suffers plastic, rather than merely elastic, deformation. Young's modulus measures the stiffness of a material by computing the ratio of stress to this quantity. For 10 points, what is this dimensionless measure of the deformation of a body, given in uniaxial form by the change in length divided by the original length?
