A simple alteration of the peridynamics correspondence principle to eliminate zero-energy deformation
Shubhankar Roy Chowdhury, Pranesh Roy, Debasish Roy +1
We look for an enhancement of the correspondence model of peridynamics with a view to eliminating the zero-energy deformation modes. Since the non-local integral definition of the…
Two-temperature continuum model for viscoplasticity in metals based on fluctuation relation
S Roy Chowdhury, D Roy, J N Reddy
A continuum plasticity model for metals is presented from considerations of non-equilibrium thermodynamics. Of specific interest is the application of a fluctuation relation that s…
A peridynamic theory for linear elastic shells
Shubhankar Roy Chowdhury, Pranesh Roy, Debasish Roy +1
A state-based peridynamic formulation for linear elastic shells is presented. The emphasis is on introducing, possibly for the first time, a general surface based peridynamic model…
Internal noise driven generalized Langevin equation from a nonlocal continuum model
Saikat Sarkar, Shubhankar Roy Chowdhury, Debasish Roy +1
Starting with a micropolar formulation, known to account for nonlocal microstructural effects at the continuum level, a generalized Langevin equation (GLE) for a particle, describi…
A Micropolar Peridynamic Theory in Linear Elasticity
S. Roy Chowdhury, Md Masiur Rahaman, Debasish Roy +1
A state-based micropolar peridynamic theory for linear elastic solids is proposed. The main motivation is to introduce additional micro-rotational degrees of freedom to each materi…
A Kushner-Stratonovich Monte Carlo Filter Applied to Nonlinear Dynamical System Identification
S Sarkar, S R Chowdhury, M Venugopal +2
A Monte Carlo filter, based on the idea of averaging over characteristics and fashioned after a particle-based time-discretized approximation to the Kushner-Stratonovich (KS) nonli…
