Quantities that connect the components of an elastic stress at some point of a linearly-elastic (or solid deformable) isotropic body with the components of the deformation at this point:
 |
where 
and 
are the normal and tangential constituents of the stress, 
are the components of the deformation and the coefficients 
and 
are the Lamé constants. The Lamé constants depend on the material and its temperature. The Lamé constants are connected with the elasticity modulus 
and Poisson's ratio 
by
 |
is also called Young's modulus and 
is the modulus of shear.
The Lamé constants are named after G. Lamé.
