Materials: Anisotropic

Description

Anisotropic material is a general form of material and its mechanical behaviour varies in each direction it is loaded, as defined by up to 21 independent parameters ( to ) and six thermal expansion coefficients . Its stress-strain relationship is expressed as:

where

= normal stresses and strains in each of the first, second and third axes respectively.

= shear stresses normal to and in each of the first, second and third axes respectively.

= user-specified material parameters.

= change in temperature.

= linear thermal expansion coefficients.
