Abstract

The concept of damage has been introduced by Rabotnov and Kachanov in 1958 for the description of creep rupture. Since then this concept has been used to account for various types of rupture occuring in metals and other kinds of solids: creep rupture, fatigue, plastic rupture. For the one-dimensional case a survey of the basic ideas as well as some recent results can be found in [1]. The three-dimensional case has been far less investigated and many conceptual problems remain to be solved. Most of these problems are related to the anisotropy of the damage and of the resulting properties, for instance the elastic response. This paper is devoted to an approach to these problems: a model will be presented for the description of the damage concept in the three-dimensional case and its consequences, as regards the induced elastic anisotropy, will be investigated in order to allow the evaluation of this model by comparison with experimental results or numerical simulation.
