The feasibility of introducing the averaged bulk modulus, which has the same attributes as other elastic moduli, is substantiated. A relationship between the Grüneisen parameter and Poisson’s ratio is discussed.
WebJul 11, 2024 · The bulk modulus of solid materials can be quite large. For steel, B= 1.60x10 11 Pa. This means that to get a volume change of 0.1% requires a pressure increase of 1.6x10 8 Pa which is 1580 times … WebThe shear yield stress k of a polycrystalline solid is related to the shear stress τy required to move a dislocation on a single slip plane: k τy 2 ≈ 3 . The uniaxial yield stress σy of a polycrystalline solid is approximately σy =2k, where k is the shear yield stress. Hardness H (in MPa) is given approximately by: H ≈3σy.
