A reductive analysis of a compartmental model for COVID-19: data assimilation and forecasting for the United Kingdom
G. Ananthakrishna, Jagadish Kumar
We introduce a deterministic model that partitions the total population into the susceptible, infected, quarantined, and those traced after exposure, the recovered and the deceased…
Influence of Visco-elastic Nature on the Intermittent Peel Front Dynamics of the Adhesive Tape
Jagadish Kumar, G. Ananthakrishna
We investigate the influence of viscoelastic nature of the adhesive on the intermittent peel front dynamics by extending a recently introduced model for peeling of an adhesive tape…
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…
Modeling the complexity of acoustic emission spectra during intermittent plastic deformation: Power laws and multifractal spectra
Jagadish Kumar, G. Ananthakrishna
Scale invariant power law distributions for acoustic emission signals are ubiquitous to several plastically deforming materials. However, power law distributions for the acoustic e…
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…
