Theoretical investigation on polar dielectric with large electrocaloric effect as cooling devices
Polar dielectric based cooling devices are
modeled as a system with two degrees of freedom and represented by either an
entropy-temperature or electric displacement-electric field plane. A typical
thermodynamic energy cyclic path is proposed for polar dielectric as cooling
devices to experience. With the influence of temperature taken into
consideration, the free energy of a thermal electrical coupling system of polar
dielectrics is formulated, and the variation of temperature and entropy, the
absorption of heat, and the work under different electric fields are calculated
for BaTiO3, Pb(ZrxTi1-x)O3, P(VDF-TrFE), and water. And the simulation results
obtained agree well with the recently published experimental data [B. Neese, et

PhD Positions Available in Mechanics of Materials at Clarkson University
Two PhD positions are available immediately in the Department of Civil & Environmental Engineering at Clarkson University, NY, US. The research program focuses on the mechanical behaviors of advanced materials including polymer microstructures, composites, nanomaterials, and biological materials. Interdisciplinary collaborations are possible. The candidates with background and interest in engineering mechanics, solid mechanics, and materials science are highly encouraged to apply.
(long distance) research cooperation..
let me know if you are interested in long distance research cooperation.
can be as simple as you get my explaination if you want/need to cite my works, or co-authoring paper in things that we can work synergically, or even research collaboration.
the only thing that i will not respond is if you ask for job....:) cant give you that.
here is some of my recent works:

How to use DFLUX to make a heat source model?
Hi, everyone.
I'm a freshman for ABAQUS User Subroutines. I'm studying laser forming and I wanna use DFLUX to make a Goldak heat source model in my simulation. But I don't know how to do with it. Are there any examples or advice about studying DFLUX?
Many thanks to you all.
Journal Club Theme of November 2011: Hierarchical Mechanics of Diatom Algae: From Atoms to Organism and Weakness to Strength
Hierarchical Mechanics of Diatom Algae: From Atoms to Organism and Weakness to Strength
This month’s iMechanica Journal Club theme is the hierarchical structure and mechanics of diatom algae, silicified organisms that use silica (“sand”) – abundantly available in the ocean – to construct strong, tough and stiff structures [1-10]. The interest in this area has been revived recently given recent advances in the combined measurement, modeling and synthesis of these materials, leading to exciting research being conducted at the interface of mechanics and biology.
Dynamic FEM: Can the timestep size be made extremely/arbitrarily small?
Dear all,
I am in the process of developing an FE code, and doing the analysis, for a class of highly nonlinear, dynamic problems in elasticity using Total Lagrangian formulation. It is well-known that for the accuracy purposes, we need to use a small timestep size (stability is not an issue for me as I am using an unconditionally stable implicit scheme for timestepping).
My doubt is whether I can use arbitrarily/extremely small time steps in the analysis for a given mesh?
