Use of elastic stability analysis to explain the stress-dependent nature of soil strength [PDF]

open access: yesRoyal Society Open Science, 2015
The peak and critical state strengths of sands are linearly related to the stress level, just as the frictional resistance to sliding along an interface is related to the normal force. The analogy with frictional sliding has led to the use of a ‘friction
