Abstract: A vast amount of past experimental investigations reported that the internal peak angle of sand was jointly governed by the density and effective stress level. Several relationships were proposed between these elements. The dependence of dilatancy characteristics on the internal state of a granular material was examined and revealed. A simple constitutive model framework was established on a basis of several well-proven and experienced relationships for granular materials to simulate their undrained shear beha… Show more

“…It can be stated that the peak angle of shear strength is composed of the critical angle of shear strength and the portion due to dilation behavior, see e.g. [33]. The ratio between the interface's shear strength and the unreinforced shear strength is quantitatively represented by the interface's shear strength coefficient a according to the following equation:…”
