In this paper, the constitutive model of the normal elastic material has been generalized in order to describe stress states accounting for different strength characteristics in different directions. With this aim, suitable stress ranges can be defined by appropriately varying the relative position between different cones, each of which expresses a particular stress constraint. The model has been formulated and implemented in the Mady code. Then, it has been applied to the study of some test cases.

Abstract
In this paper, the constitutive model of the normal elastic material has been generalized in order to describe stress states accounting for different strength characteristics in different directions. With this aim, suitable stress ranges can be defined by appropriately varying the relative position between different cones, each of which expresses a particular stress constraint. The model has been formulated and implemented in the Mady code. Then, it has been applied to the study of some test cases.
