Instability and Bifurcation for Inelastic Geomaterials

Chambon, R.

During the past issues of the workshop on localization and bifurcation in soils and rocks, the two words instability and bifurcation are used by many participants and induce many strong discussions. I am convinced that most of these discussions are only semantic ones and that indeed this is due to two main things. In the best case discussion is triggered by the fact that different people have different definitions of these words, in the worst case some people have no explicit definition of the word used. We try in this paper once more to put forward the intrinsic difficulties of true instability and bifurcation studies for geomaterials and see how numerical tools can finally help us.
