Elastic potential of deformed anisotropic body

Division of elastic energy of anisotropic body strain is carried out by the safety criteria of the ball part of stresses, strain and strain work for limiting state. It is shown that in the general case of loading the components of the ball part of stresses and strains are not equal to the one-third of their first invariants. Values of these components as the values of a deviator part of the elastic potential depend on a type of stress-strained state and direction of loading (strain)
