A Thermodynamic Model of Physical Gels
Physical gels are characterized by dynamic cross-linksthat are constantly created and broken, changing its state between solid andliquid under influence of environmental factors.

In the study of thermoelastic actuation of dielectric elastomer, we can write the Helmholtz free-energy as a function of stretch ratio, nominal electric displacement and temperature (T).
The entropy (S) is the negative partial differential coefficient of W with respect of temperature (T). And we can see the change of S is due to three components: deformation, heat conduction and polarization. In an isothermal state, the deformation part has been fully investigated by Arruda and Boyce in 1993, but the polarization-induced entropy (Sp) has not been clearly stated.
Since my research touches on the basics of QM, I have developed this habit of visiting arXiv.org every now and then. Last week or so, at arXiv.org, I found a couple of interesting articles on physics in general. I would like to share these with you.
Dear all,
My name is Adrien Haxaire. I am currently Associate Professor at LGCIE, INSA Lyon, France, until end of August. I am looking for a
Post-Doc position in geomechanics in Europe.
During my PhD, I developped a thermodynamical model capable of describing coupled THMC phenomena in unsaturated porous media. It was implemented in Cast3M.
I am very interested in chemical reactions in porous media, their modelling and implementation. I am also interested in the field of CO2 sequestration.

INELASTICITY OF MATERIALS- An Engineering Approach and a Practical Guide
by Arun R Srinivasa (Texas A&M University, USA) & Sivakumar M Srinivasan (Indian Institute of Technology, Madras, India) |
Please allow me to note that I have recently published in Philosophical Magazine a paper that presents a general approach to Gibbsian surface thermodynamics that includes a treatment of solid surfaces. It can be accessed through the following link:
http://www.informaworld.com/smpp/content~db=all~content=a792987191
This position is located in Lancaster, California.
Does anyone knows where I can find any paper discuss the existence of potential functinoal for materials that violate the maximum plastic dissipation principle (due to non-convex yield function and/or non-associately fluw rule)?
