Catastrophic thinning of dielectric elastomers
Consider a thin dielectric plate with conducting faces: when will it break if a voltage is applied? If it is rigid it will break once its dielectric strength is overcome by the voltage. But what if it is highly stretchable, like the elastomers used for soft actuators, stretchable electronics, or energy harvesters? The precise answer to that question is not known.
A novel class of highly efficient and accurate time-integrators in nonlinear computational mechanics
A new class of time-integrators is presented for strongly nonlinear dynamical systems. These algorithms are far superior to the currently common time integrators in computational efficiency and accuracy. These three algorithms are based on a local variational iteration method applied over a finite interval of time.
Postdoctoral position in mesoscale plasticity
The School of Materials Engineering at Purdue University invites applications for a Postdoctoral Research Associate position in the area of Computational Mesoscale Plasticity. The successful candidate will model plasticity of single crystals using continuum dislocation dynamics and perform computational solution using finite element method. We are particularly interested in applicants with expertise in computational materials science and/or computational mechanics, good background in elasticity and plasticity theory, and knowledge of dislocation dynamics.

A Continuum Model for Dislocation Pile-up Problems (Accepted by Acta Materialia)
A continuum dislocation pile-up model is developed to solve problems with arrays of edge dislocations on one or multiple slip planes. The model solves pile-up problems in a discrete dislocation dynamics manner. The effect of anisotropy and stacking fault energy can be naturally modeled. The model is validated by reproducing the solutions of problems for which analytical solutions are available. More complicated phenomena such as interlacing and randomly distributed dislocations are also simulated.

Master Mechanics of Materials and Structures for Civil Engineering and Transportation Systems, University Paris-East, France
The master Mechanics of Materials and Structures for Civil Engineering and Transportation Systems (MMSCT) is a one-year program offered at UPEM (University Paris-East Marne-la-Vallée), France (20 min from Paris center by transportations). The program aims at providing the students with deep scientific and technical knowledge about the multiscale modelling, over a broad range of scales, of complex materials and structures.
