A state parameter for sands
K. Been,Michael Jefferies +1 more
TL;DR: In this paper, the authors present an appropriate physical parameter, termed the state parameter, that combines the influence of void ratio and stress level with reference to an ultimate (steady) state to describe sand behaviour.

Nonlinear Failure Envelope for Soils
TL;DR: In this paper, a simple expression for the variation of the angle of shearing strength with stress level is proposed, and the nonlinear failure envelope in terms of effective stresses for most soil and rock types can be described by a simple fourparameter expression of hyperbolic type.

Shear strength response of some geological materials in triaxial compression
TL;DR: In this paper, a more realistic and responsive shear strength criterion, involving only two different strength parameters, that remain practically constant with the applied stress, is advocated to represent non-linear response that minimizes the drudgery by conducting a number of triaxial tests on the material.
