In this paper a hypoplastic model proposed by Gudchus and Bauer is presented which is apt to describe the mechanical behaviour of loose and dense sand within a wide range of pressures and densities using a single set of constants. State changes are assumed to depend on the current void ratio. the Cauchy stress tensor and the stretching tensor. The constitutive Equation is of the rate ... https://darthomes.shop/product-category/placemats/
