On behalf of the organizing committee, I cordially invite your participation in Symposium on Mechanics and
Physics of Soft Matter, as part of the 13th Pan-American Congress of Applied Mechanics (PACAM XIII), to be held in Houston, Texas, May 22-24, 2013.
The Department of Mechanical Engineering at the University
of Houston (UH) invites applications for a tenured faculty position at the Full
Professor level beginning Fall 2013 or later. Successful candidates are
expected to establish an internationally recognized dynamic research program in
the area of experimental biomechanics and mechanobiology. Special preference
would be given to those pursuing cellular level and/or single molecule studies
of living systems with emphasis on healthcare applications. Highly qualified
Dear All,
I was wondering whether anyone here knows any companies or institutions which can supply the complete Split Hopkinson Pressure Bars apparatus. Actually I found a website (http://www.thiot-ingenierie.com/accueil-fr.php?lang=en)
I sent email them. But they did not give answer.
Thanks for your aswer

Dear all,
I am working on an UMAT subroutine. The problem I have is that it works on windows system, however, when I run it on Linux environment I got the error msg "system error "Illegal floating point operation" (signal 8)."
I checked the subroutine for many times and also it works under windows, so it can not come from the problem of dividing by zero or something like that.
Does anyone know why the Signal 8 error happens? I think many subroutine programmers have the same problem.
Thanks

Fully funded PhD studentship at The Open Univeristy campus, Milton Keynes, UK. The aim of this project is to optimise experimental techniques such as digital image correlation (DIC) and focused ion beam (FIB) hole drilling to investigate the micro scale stresses and strains occurring during martensitic transformations. The techniques will be applied to a range of materials from simple steels to complex shape memory alloys. There will also be scope within the project to study martensitic alloys using central facilities such as the ILL, ESRF and Diamond light source.
Although the cantilever beam has been widely used as a sensor to measure various physical quantities, important issues such as how residual stress affects its bending stiffness and what are the underlying physical origins have not been fully understood. We perform both theoretical analyses and finite-element simulations to demonstrate for the first time that without changing the material tangent stiffness, residual stress within the beam can directly influence the bending stiffness of the beam. This direct influence arises from two origins: geometry nonlinearity and Poisson’s ratio effect.

Hi
I am thinking of a SMART HEADPHONE for people who are listenning to the music all the time for their saftey an their convenience and the people who tries to communicate with them. How SMART? The danger for such people is that they can not hear the alarm of the danger, like the horn of a vehicle. And also, sometimes they are called but they do not hear and consequently they do not show any reaction. This is so bothering for other people.
The tech:
In this paper, dislocation climb is incorporated in a two-dimensional discrete dislocation dynamics model. Calculations are carried out for polycrystalline thin films, passivated on one or both surfaces. Climb allows dislocations to escape from dislocation pile-ups and reduces the strain-hardening rate, especially for fully passivated films. Within the framework of this model, climb modifies the dislocation structures that develop during plastic deformation and results in the formation of pile-ups on slip planes that do not contain any dislocation sources.
