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…
