Abstract: The shear band formation and orientation in anisotropic granular materials have been studied. The anisotropy is described by making use of the microstructure tensor that complies with principles of continuum mechanics and ...

Abstract: Some theoretical criteria are set forth to study the onset of a strong and/or a weak discontinuity in hypoplastic granular materials under some simple motion fields. The theoretical criteria were based on direct analysis, ...

Abstract: An important point of shear banding is that during the rotation of principal stress directions, out-of-axes deformation plays a significant role and leads to noncoaxiality between principal stress and principal plastic-strain-rate ...

Abstract: Overlooking the anisotropic behavior of soil with directional shear strength parameters can lead to unrealistic estimation of the actual limit load. This research is focused on the effect of the shear strength anisotropy ...

Abstract: The limit state in hypoelastic materials, analogous to the failure or yield in classical theory of plasticity, along with the bifurcation point, corresponding to a localized instability, have been studied. Analytical ...

Abstract: This paper aims at analyzing the active and passive lateral earth pressures exerted on retaining walls due to the anisotropic medium of dry and noncohesive backfill subjected to the modified pseudodynamic earthquake loading. ...

Abstract: The dynamical behavior of a system containing a surface foundation atop a fluid-conveying pipe that is embedded in soil beneath the foundation is investigated. A Winkler–Voigt model is presented to simulate the interaction ...
