Stochasticity of fatigue failure times in sheared glasses
Swarnendu Maity, Pushkar Khandare, Himangsu Bhaumik +2
Fatigue failure occurs when a solid is subjected to repeated, cyclic loading. Glasses subjected to cyclic shear deformation have recently been investigated using computer simulatio…
Cyclically sheared colloidal gels: structural change and delayed failure time
Himangsu Bhaumik, James E. Hallett, Tanniemola B. Liverpool +2
We present experiments and simulations on cyclically sheared colloidal gels, and probe their behaviour on several different length scales. The shearing induces structural changes i…
Yielding in colloidal gels: from local structure to meso-scale strand breakage and macroscopic failure
Himangsu Bhaumik, Tanniemola B. Liverpool, C. Patrick Royall +1
We study creep flow and yielding of particulate depletion gels under constant shear stress, combining data on different length and time scales. We characterise the breakage of meso…
Mechanical regularization
Himangsu Bhaumik, Daniel Hexner
Training materials through periodic drive allows to endow materials and structures with complex elastic functions. As a result of the driving, the system explores the high dimensio…
Loss of material trainability through an unusual transition
Himangsu Bhaumik, Daniel Hexner
Material training is a method to endow materials with specific responses through external driving. We study the complexity of attainable responses, as expressed in the number of si…
Yielding transition of a two dimensional glass former under athermal cyclic shear deformation
Himangsu Bhaumik, Giuseppe Foffi, Srikanth Sastry
We study numerically the yielding transition of a two dimensional model glass subjected to athermal quasi-static cyclic shear deformation, with the aim of investigating the effect…
Avalanches and Structural Change in Cyclically Sheared Silica Glass
Himangsu Bhaumik, Giuseppe Foffi, Srikanth Sastry
We investigate avalanches associated with plastic rearrangements and the nature of structural change in the prototypical strong glass, silica, computationally. Although qualitative…
Critical properties of deterministic and stochastic sandpile models on two-dimensional percolation backbone
Himangsu Bhaumik, S. B. Santra
Both the deterministic and stochastic sandpile models are studied on the percolation backbone, a random fractal, generated on a square lattice in -dimensions. In spite of the un…
Stochastic sandpile model on small-world networks: scaling and crossover
Himangsu Bhaumik, S. B. Santra
A dissipative stochastic sandpile model is constructed on one and two dimensional small-world networks with different shortcut densities where and represent a regular…
Sandpile model on Scale Free Networks with preferential sand distribution: a new universality class
Himangsu Bhaumik, S. B. Santra
A two state sandpile model with preferential sand distribution is developed and studied numerically on scale free networks with power-law degree () distribution, {\em i.e.}: $P_…
Dissipative stochastic sandpile model on small world network : properties of non-dissipative and dissipative avalanches
Himangsu Bhaumik, S. B. Santra
A dissipative stochastic sandpile model is constructed and studied on small world networks in one and two dimensions with different shortcut densities , where represents r…
Crossover from rotational to stochastic sandpile universality in the random rotational sandpile model
Himangsu Bhaumik, Jahir Abbas Ahmed, S. B. Santra
In the rotational sandpile model, either the clockwise or the anti-clockwise toppling rule is assigned to all the lattice sites. It has all the features of a stochastic sandpile mo…
Critical properties of a dissipative sandpile model on small world networks
Himangsu Bhaumik, S. B. Santra
A dissipative sandpile model (DSM) is constructed and studied on small world networks (SWN). SWNs are generated adding extra links between two arbitrary sites of a two dimensional…
