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.

What does a dislocation look like in a spherical geometry, and how does it migrate in such a structure? We report here the counterintuitive motion of the 1/2⟨0001⟩ edge dislocation in carbon onions from the outer surface to the inner core, i.e. from a low pressure surface to a high pressure core, rather than from the core to the surface as expected due to a surface image force. Maybe you can help us to explain this peculiar phenomenon.

I am studying the effect of intermediate microfabric on clay's mechanical behavior. In order to develope the constitutive model for clay considering its microfabric, I want to use fabric tensor. If any good paper or study material on fabric tensor is available then please send me.

Thanks
