thesis
hi everyone ,
im finding the subject of my thesis(in master science) i will be glad if anyone offer me the subject with satisfactory future , my tendency is applyed mechanic in stress !
please explain about the future job,
thank you

Inverse
It is not recommended to Invert a Matrix in Numerical Analysis. Solving with Factorization methods (L.U, L.D.Lt, ..) is better than Solution with Direct Inverse. This is due to Numerical Errors (roundoff) and/or ill-Conditioned problems. In case of you need to use an Inverse, you are advised to take care about using existing algorithms which can't be exact in all applications.
Symposium on Mechanics and Physics of Soft Matter
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.
Full Professor Opening – Experimental Biomechanics, Mechanobiology and Biophysics
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
Hopkinson Bar Test
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

Abaqus Error Singnal 8
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

PhD Studentship: In-situ quantification of interphase stress during martensitic transformations, Open University, UK
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.
Direct influence of residual stress on the bending stiffness of cantilever beams
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.
