Energy dissipation in high speed impact on granular media
Manish Kumar Mandal, Saikat Roy
In this work, we thoroughly investigate the impact process on the granular media in the limit when the ratio of the impact velocity to the acoustic speed becomes of the order of 0.…
Dipole Screening in Pure Shear Strain Protocols of Amorphous Solids
Chandana Mondal, Michael Moshe, Itamar Procaccia +1
When amorphous solids are subjected to simple or pure strain, they exhibit elastic increase in stress, punctuated by plastic events that become denser (in strain) upon increasing t…
Micro-mechanical insights into the stress transmission in strongly aggregating colloidal gel
Divas Singh Dagur, Yezaz Ahmed Gadi Man, Saikat Roy
Predicting the mechanical response of the soft gel materials under external deformation is of paramount importance in many areas, such as foods, pharmaceuticals, solid-liquid separ…
Spatial stress correlations in strong colloidal gel
Divas Singh Dagur, Chandana Mondal, Saikat Roy
In this work, we systematically investigate for the first time the nature of stress correlations in soft colloidal gel materials which support tensile and compressive forces as wel…
Experimental and Numerical Verification of Anomalous Screening Theory in Granular Matter
Chandana Mondal, Michael Moshe, Itamar Procaccia +3
The concept of mechanical screening is widely applied in solid-state systems. Examples include nucleation of defects in crystalline materials, scars and pleats in curved crystals,…
Anomalous Elasticity and Screening in Amorphous Solids
Anaël Lemaître, Chandana Mondal, Michael Moshe +3
Amorphous solids appear to react elastically to small external strains, but in contrast to ideal elastic media, plastic responses abound immediately, at any value of the strain. Su…
Frictional Granular Matter: Protocol Dependence of Mechanical Properties
Anaël Lemaître, Chandana Mondal, Itamar Procaccia +3
Theoretical treatments of frictional granular matter often assume that it is legitimate to invoke classical elastic theory to describe its coarse-grained mechanical properties. Her…
Stress Correlations in Frictional Granular Media
Anael Lemaitre, Chandana Mondal, Itamar Procaccia +1
This paper investigates whether in frictional granular packings, like in Hamiltonian amorphous elastic solids, the stress autocorrelation matrix presents long range anisotropic con…
Modeling the Generic Breakthrough Curve for Adsorption Process
Saikat Roy, Arun S. Moharir
This work is aimed at understanding the basic principles of adsorption process in great details as adsorptive separation process has broad applications in the industry. To this end…
Diffusion in Agitated Frictional Granular Matter Near the Jamming Transition
H. G. E. Hentschel, Itamar Procaccia, Saikat Roy
We study agitated frictional disks in two dimensions with the aim of developing a scaling theory for their diffusion over time. As a function of the area fraction and mean-squa…
Scaling Theory of Giant Frictional Slips in Decompressed Granular Media
H. George E. Hentschel, Itamar Procaccia, Saikat Roy
When compressed frictional granular media are decompressed, generically a fragile configuration is created at low pressures. Typically this is accompanied by a giant frictional sli…
Force Distributions in Frictional Granular Media
V. S. Akella, M. M. Bandi, H. George E. Hentschel +2
We report a joint experimental and theoretical investigation of the probability distribution functions (pdf's) of the normal and tangential (frictional) forces in amorphous frictio…
A theory for the compression of two dimensional strongly aggregated colloidal networks
Saikat Roy, Mahesh S Tirumkudulu
The consolidation of suspended particulate matter under external forces such as pressure or gravity is of widespread interest. In this work, we derive a constitutive relation to de…
