L'approche energetique en mecanique des materiaux granulaires

Abstract

This communication establishes first, that basis of discontinuous granular materials mechanics, are the explicit result of a new approach of the physics of energy dissipation by friction, and second, that these mechanics of discontinua, transposed to the equivalent continuous media, as used in geomechanics, is directly responsible for a large set of practical properties of these materials, part of the fundamentals of Soil Mechanics. These physics of energy dissipation are developped on the original concept of energy rate tensor of internal actions.
