A theoretical model is presented suitable for the description of the damaging process in brittle materials. Damage is defined by a second-order symmetric tensor and activates at different orientations to the principal strain directions, according to the sign of the principal strain which attains a damage threshold. The capabilities of the model in describing the mechanical response of material elements subjected to non-proportional stresses are illustrated.

Abstract
A theoretical model is presented suitable for the description of the damaging process in brittle materials. Damage is defined by a second-order symmetric tensor and activates at different orientations to the principal strain directions, according to the sign of the principal strain which attains a damage threshold. The capabilities of the model in describing the mechanical response of material elements subjected to non-proportional stresses are illustrated.File in questo prodotto:
