Hooke law

A law describing the relation between stress and deformation in an elastic body, within a certain range. It states that a small deformation is proportional to the forces applied to the body, i.e. the deformation tensor is a linear function of the stress tensor :

where is the Kronecker symbol, is the modulus of compression and is the shear modulus. See Elasticity, mathematical theory of.

In its simplest form the law was experimentally established by R. Hooke in 1660.
