The minimum energy principle in description of nonlinear properties of orthotropic material

In this paper the conception of theoretical determine the relations between material experimental characteristics is presented.On the base of stress-strain relations for nonlinear elastic anisotropic material and geometrical interpretation of deformation state,the general form of strain energy density function was introduced.Using this function and variational methods the relations between material characteristics were achieved.All considerations are illustrated by a short theoretical example.
