Statistical mechanics of a dielectric polymer chain in the force ensemble
Matthew Grasinger, Kaushik Dayal, Gal deBotton +1
Constitutive modeling of dielectric elastomers has been of long standing interest in mechanics. Over the last two decades rigorous constitutive models have been developed that coup…
On the dissipation at a shock wave in an elastic bar
Prashant K. Purohit, Rohan Abeyaratne
This paper aims to quantitatively relate the energy dissipated at a shock wave in a nonlinearly elastic bar to the energy in the oscillations in two related dissipationless, disper…
Wave manipulation using a bistable chain with reversible impurities
Hiromi Yasuda, Efstathios G. Charalampidis, Prashant K. Purohit +2
We systematically study linear and nonlinear wave propagation in a chain composed of piecewise-linear bistable springs. Such bistable systems are ideal testbeds for supporting nonl…
Bacterial activity hinders particle sedimentation
Jaspreet Singh, Alison E. Patteson, Bryan O. Torres Maldonado +2
Sedimentation in active fluids has come into focus due to the ubiquity of swimming micro-organisms in natural and industrial processes. Here, we investigate sedimentation dynamics…
A continuum model for the growth of dendritic actin networks
Rohan Abeyaratne, Prashant K. Purohit
Polymerization of dendritic actin networks underlies important mechanical processes in cell biology such as the protrusion of lamellipodia, propulsion of growth cones in dendrites…
Elasticity as the basis of allostery in DNA
Jaspreet Singh, Prashant K. Purohit
Allosteric interactions in DNA are crucial for various biological processes. These interactions are quantified by measuring the change in free energy as a function of the distance…
