Faculty Positions in Aerospace Engineering at the Georgia Institute of Technology
The Daniel Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology in Atlanta, GA, invites nominations and applications for five tenure-track faculty positions. Applications are sought from candidates with expertise in the traditional aerospace disciplines, promising new research areas, and cross-cutting interdisciplinary fields. Areas of interest may include, but are not limited to, aerodynamics, design and manufacturing, structures and solid mechanics, and autonomy for aerospace systems.
coupled analysis with umat
Dear all,
I want to do coupled analysis(pore fluid/stress) in abaqus. I use a umat subroutin for define my material (that is soil). other hand I want to use void ratio in permeability. I define permeability in material but I want to use void ratio in my subroutin and the void ratio can changed and dont be constant during run. Do anybody know, how can I changed void ratio with my variables defined in umat?
Of course, I tried to use user field variables, but in window of Pearmibilty there isnt icon of "number of field variables" and I couldnt define "field" for void ratio.
Micromechanics Simulation Challenge
As the importance of micromechanics is increasingly realized in composites design & manufacturing at the industry level, cdmHUB is launching a Micromechanics Simulation Challenge for the purpose of establishing the best practices for homogenization and dehomogenization needed in composites design and manufacturing.
MIT Faculty Positions in Civil & Environmental Engineering
The Department of Civil and Environmental Engineering invites applications for several tenure-track faculty positions to begin July 2015 or thereafter. Appointments will be at the assistant or untenured associate professor level. In special cases, a senior faculty appointment may be possible. We will consider exceptional candidates in a range of areas, broadly defined. Further information about the department can be found at this page.
PhD positions (TA/RA) available at Penn State
We are looking for PhD candidates to conduct research at the following two interdisciplinary subfields, starting from Spring of 2015. Interested individuals are encouraged to apply (suz10 [at] psu.edu)
1) Mechanics in electrochemistry. We develop atomistically informed continuum mechanics models, coupling mechanics and lithium reaction and diffusion to account for a wide range of in-situ experimental phenoemna. Some recent publications:

material grade details
i want to know the material grade which is used in APPLE phones/laptop circuit chassis
i know that aluminium is used .grade please????
Representative Volume Element Calculations under Constant Stress Triaxiality, Lode Parameter, and Shear Ratio
Recent experiments showed that the Lode parameter, which distinguishes between axisymmetric and shear dominated stress states, has a profound effect on material ductility, especially at low stress triaxiality. Consequently, the theoretical framework for void growth and coalescence is currently being revisited, which often involve performing representative volume element (RVE) calculations. The present study investigates an RVE composed of a cubic unit cell containing a spherical void at its center.
Fatigue of multiscale composites with secondary nanoplatelet reinforcement: 3D computational analysis
3D numerical simulations of fatigue damage of multiscale fiber reinforced polymer composites with secondary nanoclay´reinforcement are carried out. Macro–micro FE models of the multiscale composites are generated automatically using Python based software. The effect of the nanoclay reinforcement (localized in the fiber/matrix interface (fiber sizing) and distributed throughout the matrix) on the crack path, damage mechanisms and fatigue behavior is investigated in numerical experiments.
