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

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.

Abstract

how to find or evaluate the damage and critical damage

damage vs plastic strain graph

Hello Sir, I am doing research on the journal "A continuum damage mechanics model for void growth and micro crack initiation". In that i am modellling the cylinder with preneck. i have applied tensile load and found the induced stress.  Now, I want to find out the damage and i need to plot the damage vs plastic strain graph and I dont know how to do it abaqus or ansys. Can u please guide me or let me know how to find out the damage and plastic strain and also suggest me the weblinks if there are any which tells about the evaluation of the damage?
