W.M. Keck Institute for Space Studies Postdoctoral Fellowships Announcement of Opportunity

Application Deadline: 5pm PST 24 November 2010

The Department of Industrial Engineering at the University of Pittsburgh anticipates an opening for a postdoctoral associate starting September 2010. The position’s primary area of research will focus on mechanics of the microforming processes and characterizing the thermomechanics of deformation at micrometer length-scales.

Constitutive relations, 2-D vs. 3-D. The starting point for modeling cellular membranes is the constitutive relations in 2-D space. It is important to set up the corresponding equations directly in two dimensions rather than to consider them as an asymptotic limit of three-dimensional relationships, like it is done in the shell theory. The main reason for the direct 2-D relations is that 3-D continuum approaches are not applicable to membranes whose thickness in on the order of magnitude of the dimension of a single molecule.

NIH-FUNDED POSTDOCTORAL FELLOWSHIP IN FINTIE ELEMENT MODELING OF OCULAR TISSUES - TWO YEAR TERM

A postdoctoral associate position at MIT is available immediately,
focused on the analysis and development of multifunctional thermal
management structures, by using theoretical and atomistic multiscale
modeling and simulation. This project specifically involves calculations
of thermal and mechanical properties of graphene based metal- and
polymer nanocomposites, with a focus on various aspects such as
interfacial transport properties, tunability, mutability and phonon
engineering. Additional aspects of the project relate to the general

Physical gels are characterized by dynamic cross-linksthat are constantly created and broken, changing its state between solid andliquid under influence of environmental factors.

Hiii alll,

How can we calculate J integral of interface fracture. I'm trying to reproduce results of Hutchinson paper crack defection at an interface between dissimilar material. But while using VCCT im confused that what value i can give for crack growth parameter G1c, G2c..how can we get G1c and G2c for an interface, is it needed. Want to find the energy release rate of deflection at the interface. The material interface is of aluminium and aluminium oxide. Please do reply.Hope u understand my problem.

Thank you...

Hello

I am working on a thesis project dealing with flow stress in cold rolling, a plane strain operation. To determine the flow stress, tensile tests were carried out. I am aware, that the engineering strain/stress hast to be transfered to the true strain/stress and then the true strain/stress from the tensile test has to be mulitplied with the Von Mises yield criterion to yield the correspondent compressive flow stress in the rolling situation.
