Abstract: We have attempted a multiscale quantification of the internal structure of granular materials. The internal structure of granular materials, i.e., the geometrical information on granular particles and their spatial ...

Abstract: A plasticity constitutive framework for modeling inherently anisotropic sand behavior is presented within a modified form of critical state soil mechanics. A second-order symmetric fabric tensor,

Abstract: Interpretation of nonlinear stress-strain behavior of a material may require differentiating the load-displacement curve constructed from experimental data. Pressuremeter and torsional shear tests in geotechnical engineering ...

Abstract: An Anisotropic Critical State Theory (ACST) for granular media is presented, which accounts for the role of anisotropic fabric at critical state. It enhances the requirements of critical values for the stress and void ratio ...

Abstract: The arrival time of the first P-wave is, among other parameters, of prime importance for pinpointing the location of an acoustic emission (AE) event source. However, it seems that determining the first P-wave arrival times ...

Abstract: The effort to model sand behavior within the framework of critical-state soil mechanics would benefit from a state variable that relates the current void ratio and mean pressure of the soil to its void ratio and mean ...
