which kind of homogenization can we use?

hello every one.

If we consider dislocation effect( GNDs) that they have proportional relation with strain gradient, does it effect on way of homogenization or not? i mean at this situation can we use any methods of homogenization ? I'm looking into size effects at micro scale on macroscopic properties.i want to be sure if self consistent method is usable to as a method or not?

Postdoctoral Position in Applied Mechanics

<p>A post-doctoral position in the general area of continuum simulations of high-strain rate impact phenomena is available in the Mechanical Engineering Department at Northeastern University. The specific goal of the project is to investigate the mechanics of cohesion following high velocity impacts. Knowledge of finite element theory, contact mechanics, plasticity and cohesive zone using customized codes and Abaqus are required. Experience with writing own finite element codes, Abaqus user subroutines and Python code will be helpful for the position.

Assistant or untenured Associate Professor - Stanford University

The Department of Electrical Engineering at Stanford University (http://ee.stanford.edu/) invites applications for a tenure-track faculty appointment at the junior level (Assistant or untenured Associate Professor) in the broadly defined field of electrical and computer engineering. The department is especially interested in candidates in robotics and autonomous systems, hardware systems, and embedded systems. Priority, however, will be given to the overall originality and promise of the candidate’s work over any specific area of specialization.

Postdoctoral Fellowship in Computational Neuroscience (but embedded in a mechanics group)

I realize this is a bit off topic from traditional iMechania job posts, however our group is primarily a computational biomechanics group. We conduct much research in the area of brain biomechanics and more recently are working to move into multiphysics and multiscale areas of brain science. This project, funded by the NIH Brain Initiative, focuses on growth and bioelectric simulations of neuronal cell networks.

Spontaneous Wettability Patterning via Creasing Instability

Surfaces with patterned wettability contrast are important in industrial applications such as heat transfer, water collection, and particle separation. Traditional methods of fabricating such surfaces rely on microfabrication technologies, which are only applicable to certain substrates and are difficult to scale up and implement on curved surfaces. By taking advantage of a mechanical instability on a polyurethane elastomer film, we show that wettability patterns on both flat and curved surfaces can be generated spontaneously via a simple dip coating process.
