Radoucissement sans formation de surfaces de glissement
Stain softening without slip surface
Laboratoire de mécanique des solides Ecole Polytechnique, 91128 Palaiseau cedex, France
Il existe quelques matériaux où la présence d'un maximum de la courbe efforts-déformations n'est pas associée à la formation d'une surface de glissement : roches et bétons fragiles, sables lâches saturés, premier maximum de l'acier doux. L'influence de la fissuration des roches est particulièrement examinée.
Abstract
The softening of some materials is not associated with slip surface formation: brittle rocks and concrete, saturated soft sands, first peak of mild steel. Rocks fissures influence is specially examinated.
