PhD Robust Optimization Viscoelastic Sandwiches

Submitted by Hamdaoui on Thu, 03/12/2015 - 20:53

Visco-elastic structures are widely employed for vibration damping. Nowadays, optimal design of these structures has become commonplace. However, operating conditions introduce variability in their performances. Taking into account this variability in the optimization loop is necessary to obtain optimal robust solutions. Recently, within an exploratory project, supported by CNRS, the modal stability method (MSP) has been applied with success to quantify variability of damping and natural frequency of frequency dependent viscoelastic sandwich structures.

Ionic Cable

Submitted by _canhuiyang on Thu, 03/12/2015 - 03:42

This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call "ionic cable", uses ions to transmit signals, and is built entirely with soft, elastic materials-elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stretched nearly eight times its original length. We describe the design, theory and experiment of the ionic cable.

Professor Richard Christensen (Stanford University) published Part III of his series of papers on the failure theory. This is a short, but interesting view-point paper. The paper is attached (JAM, April issue, 2015).

Postdoctoral position at SISSA-International School for Advanced Studies

Submitted by Giovanni Noselli on Sun, 03/08/2015 - 11:58

A postdoctoral position is open at SISSA (http://www.sissa.it/) within the research group SISSA-mathLab (http://mathlab.sissa.it/). Prof. Antonio DeSimone (PI of the ERC Advanced Grant 340685-MicroMotility) is seeking a postdoctoral researcher to carry out an experimental activity focused on the study of low Reynolds number micro-swimmers. The postdoctoral researcher is expected to collaborate with other scientists of the group. A suitable candidate should have a strong background as an experimentalist.

dislocation dynamics

# Finite Element modeling

Semiconductors

Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of dislocations in strained semiconductor structures. The major task of this project is the development of an interface between the Dislocation Dynamics program (ParaDiS) with a general purpose Finite Element Method (FEM) program (such as ABAQUS). Molecular dynamics simulations may be required to provide physical input to the Dislocation Dynamics model.
