Effective dimensionality of the Portevin - Le Chatelier effect
A. Chatterjee, N. Gayathri, A. Sarkar +2
Tensile tests have been carried out by deforming polycrystalline samples of substitutional Al-2.5%Mg alloy at room temperature at a range of strain rates. The Portevin - Le Chateli…
Markov Property of Continuous Dislocation Band Propagation
A. Chatterjee, A. Sarkar, Sourav Bhattacharya +3
Tensile tests were carried out by deforming polycrystalline samples of substitutional Al-2.5%Mg alloy at room temperature for a range of strain rates. The Portevin-Le Chatelier (PL…
Recurrence analysis of the Portevin-Le Chatelier effect
A. Sarkar, Charles L. Webber, P. Barat +1
Tensile tests were carried out by deforming polycrystalline samples of Al-2.5%Mg alloy at room temperature in a wide range of strain rates where the Portevin-Le Chatelier (PLC) eff…
Molecular dynamics simulation of rapid solidification of Aluminum under pressure
A. Sarkar, P. Barat, P. Mukherjee
Molecular dynamics simulation study based on the EAM potential is carried out to investigate the effect of pressure on the rapid solidification of Aluminum. The radial distribution…
X-Ray diffraction studies on asymmetrically broadened peaks of heavily deformed Zirconium based alloys
A. Sarkar, P. Mukherjee, P. Barat
The diffraction peaks of Zircaloy-2 and Zr-2.5%Nb alloys at various deformations are found to be asymmetric in nature. In order to characterize the microstructure from these asymme…
Effect of meditation on scaling behavior and complexity of human heart rate variability
A. Sarkar, P. Barat
The heart beat data recorded from samples before and during meditation are analyzed using two different scaling analysis methods. These analyses revealed that mediation severely af…
