La dilatance des roches
Dilatancy of rocks
Laboratoire de tectonophysique — U.P.S.-I.N.S.A. Toulouse, France
Le comportement dilatant des roches fragiles, résultant de leur microfissuration, est analysé succinctement, notamment le seuil, la relation contrainte-déformation et l'évolution sous cycles. Mention particulière est consacrée à l’anisotropie, initiale ou induite.
Abstract
The dilatant behaviour of brittle rocks, resulting of the microcracks, is briefly analysed, specially the limit, the stress-strain relation and the evolution under cycles. The initial or induce anisotropy is particularly outlined.
