Symposium on Multi-physics of Materials and Interfaces @ USNCTAM 2010
Dear Colleagues:
As a part of the 16th US National Congress of Theoretical and Applied Mechanics conference (from June 27 to July 2, 2010 at Penn State University), we are organizing a symposium on the multi-physics, or the coupling among physical domains (thermal, electrical, mechanical, magnetic, optical, chemical to name a few).
A Geometric Theory of Thermal Stresses
In this paper we formulate a geometric theory of thermal stresses.
Given a temperature distribution, we associate a Riemannian
material manifold to the body, with a metric that explicitly
depends on the temperature distribution. A change of temperature
corresponds to a change of the material metric. In this sense, a
temperature change is a concrete example of the so-called
referential evolutions. We also make a concrete connection between
our geometric point of view and the multiplicative decomposition

MODELLING OF MODEIII IN ABAQUS
HELLO SIR!
i have modelled MODEIII case in FRACTURE MECHANICS IN abaqus
.
PLEASE TELL ME PINNED BOUNDARY CONDITIONS AT WHICH EDGE/FACE WILL BE APPLIED IF I MODEL FULL MODEL FOR OUT OF PLANE SHEAR LOADING,i.e, MODEIIII case
Moving Heat Source in Gmaw
Dear Sir/Madam,
i m quite new wd the ansys and was trying to simulate a problem of moving heat source in GMAW and has to move wd some Heat flux on the plate .how could i model heat distribution of the GMAW and how could i move it wd some velocity..
i hope i m clear,plz help me out.
Thank You,

A new Technical Committee on Soft Materials
A growing number of mechanicians are entering the field of soft materials, such as polymers, gels, and tissues. While they interact with researchers in technical societies traditionally identified with the field, they also maintain connection with researchers in applied mechanics.

Hi all,
A new Aeroelasticy course is offered at San Diego State University.

VUMAT for Nitinol --- why VUMAT and not UMAT?
Dear all,
I'm new in imechanica. I need some informations about VUMAT for Nitinol. I would like to implement in fortran a subroutine for the behaviour of shape memory alloy.I looked for some subroutines already implemented but they have been developed in the implicit way.
It's true that with the VUMAT(explicit) I could have some problems of stability and convergence.Could someone suggest me any reason to make this model in the VUMAT?I know that in VUMAT I can't redifine the time increment so before running the analysis It's important to pay attention on Dt.
