New papers on thermodynamics and mechanics of surfaces

Submitted by Robert C. Cammarata on

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:

potential functional for material exhibts non-associative elastoplastic response

Submitted by WaiChing Sun on

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)?

Free Energy

Submitted by Zhigang Suo on

For a system in thermal contact with the rest of the world, we have described three quantities: entropy, energy, and temperature. We have also described the idea of a constraint internal to the system, and associated this constraint to an internal variable.

Strain gradient plasticity: the flow rule of Fleck and Hutchinson violates thermodynamics ?

Submitted by Mike Ciavarella on

A recent paper on JMPS has seriously questioned the foundation of the SGP theory of Fleck and Hutchinson.  The matter is not simple, but is it a good bench test for imechanica to discuss?
