Electromagnetic (EM) waves, traditionally used for purposes such as geophysical characterization, impact properties to be measured. This paper describes the effects of radio frequency (RF) waves on hydraulic conductivity glass beads and natural sand. A series tests was conducted using a customized, rigid-wall, cylindrical permeameter inside resonant cavity made Plexiglas covered with electrical...

Abstract The study of failure mechanisms from a microperspective demands comprehensive understanding the initiation and evolution shear banding within granular materials. However, this topic is not fully understood due to technical constraints in continuous quantification degree visualization particle interactions soil specimens their inherent opacity. This paper reports possibility acoustic em...

A roadmap is presented to transition seamlessly from an image to a predictive computational model for granular materials. So far, constitutive modelling in granular materials has been based on macroscopic experimental observations. Here, the point of departure is the basic granular scale where kinematics, contact forces and fabric control the macroscopic mechanical behaviour of the material. Ne...
