Logarithmic Compaction in a 3D Model for Granular Media

The present custom-made fluidic device was designed for the mechanical stimulation and characterization of cartilage micropellets and validated here using collagen- and alginate-based

This behavior is observed for a large range of Γ (figure 4b). This shows that, for a given tapping process, the value of the packing fraction at stationary state does not depend on

To summarize, the new instability presented in this paper leads to a vortices formation during compaction of anisotropic granular media at relatively low tapping intensity. Below

Figure 2 shows the following kinematic fields: incremental displacement V , deviatoric strain  s and volumetric strain  v measured between eight strain increments in a biaxial test

on the important observation that granular materials do not conserve energy while the entropy S is well defined they proposed to consider the volume V to replace the internal energy
