The behavior of sand crushing will appear when the confining pressure is up to a certain value, which results in disappearing of the positive dilatancy of sand. Adopting a new hardening parameter with the crushing stress, an elastoplastic constitutive model considering sand crushing is proposed. Comparing the conventional triaxial compression test results with the model prediction, it shows that the...
This paper reports an experimental investigation into the inherent anisotropy and particle breakage of natural Aqaba sand. The natural sand specimens were subjected to one dimensional compression to induce breakage. The grain size distributions of the specimens were obtained before and after the application of the stresses. Thereafter, the sand shear strength parameters were assessed using direct...
