New unloading criterion for enhancing multi-stage triaxial tests based on radial strain gradient
This paper presents a new criterion for determining the unloading points quantitatively and consistently in a multi-stage triaxial test. The radial strain gradient (RSG) is first introduced as an arc tangent function of the rate of change of radial strain to time. RSG is observed to correlate closel...
