A computational model of hydrostatically coupled dielectric elastomer (HCDE) actuators
Abstract:A hydrostatically coupled dielectric elastomer (HCDE) actuator consists of two membranes of a dielectric elastomer, clamped with rigid circular rings. Confined between the membranes is a fixed volume of a fluid, which couples the movements of the two membranes when a voltage or a force is applied. This paper presents a computational model of the actuator, assuming that the membranes are neo-Hookean, capable of large and axisymmetric deformation. The voltage-induced deformation is described by the model of ideal dielectric elastomer. The forc

direct correspondence betwene stress-thermal condctivity-strain
Using a new experimental setup have now proved that one could actually draw a thermal conductivity-strain relationship in the same way as stress-strain relation!
What remains to be seen is that whether this relationship is tensorial or not! Details are in the paper..

Modelling a crack using ansys
How can i model a crack in a solid block(3D) in ansys. Do i need to use quater point elements at the crack tip or a general mesh will be sufficient.?

Abstract
Designing copper–zirconium based nanowires for improving yield strength and plasticity via configuring surface atoms
Following our previous work on Cu-Zr nanowire system, in this paper we have shown improvement in various thermo-mechanical properties of nanowire via manipulating the surface atoms. The paper titled "Designing copper–zirconium based nanowires for improving yield strength and plasticity via configuring surface atoms" by Vijay Kumar Sutrakarand D Roy Mahapatra has been published in Journal of Nanoparticle Research.
