Phase transition of three-dimensional finite-sized charged dust clusters in a plasma environment
Hirakjyoti Sarma, Ritupan Sarmah, Nilakshi Das
The dynamics of a harmonically trapped three-dimensional Yukawa ball of charged dust particles immersed in plasma is investigated as function of external magnetic field and Coulomb…
General framework for acoustic emission during plastic deformation
Jagadish Kumar, Ritupan Sarmah, G. Ananthakrishna
Despite the long history, so far there is no general theoretical framework for calculating the acoustic emission spectrum accompanying any plastic deformation. We set up a discrete…
Projecting Low Dimensional Chaos from Spatio-temporal Dynamics in a Model for Plastic Instability
Ritupan Sarmah, G. Ananthakrishna
We investigate the possibility of projecting low dimensional chaos from spatiotemporal dynamics of a model for a kind of plastic instability observed under constant strain rate def…
A unified model for the dynamics of driven ribbon with strain and magnetic order parameters
Ritupan Sarmah, G. Ananthakrishna
We develop a unified model to explain the dynamics of driven one dimensional ribbon for materials with strain and magnetic order parameters. We show that the model equations in the…
Dynamics of strain bifurcations in magnetostrictive ribbon
Ritupan Sarmah, G. Ananthakrishna
We develop a coupled nonlinear oscillator model involving magnetization and strain to explain several experimentally observed dynamical features exhibited by forced magnetostrictiv…
Hidden order in serrated flow of metallic glasses
Ritupan Sarmah, G. Ananthakrishna, B. A. Sun +1
We report results of statistical and dynamic analysis of the serrated stress-time curves obtained from compressive constant strain-rate tests on two metallic glass samples with dif…
