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: This paper presents an experimental and analytical progressive collapse-resistance evaluation of reinforced concrete (RC) frame substructures under monotonic vertical displacement of a side column, simulating a column ...

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: This paper presents an experimental and analytical progressive collapse-resistance evaluation of reinforced concrete (RC) frame substructures under monotonic vertical displacement of a side column, simulating a column ...

Abstract: The buckling behavior of elastic space rods under torsional moment is studied theoretically. A consistent method is developed to identify the buckling torsional moment as well as to trace the postbuckling path. Since this ...

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 ...
