In our recent paper, we examined the energy conservation for the current schemes of applying active deformation in molecular dynamics (MD) simulations. Specifically, two methods are examined. One is scaling the dimension of the simulation box and the atom positions via an affine transformation, suitable for the periodic system. The other is moving the rigid walls that interact with the atoms in the system, suitable for the non-periodic system.

Dear all,

We would like to draw your attention to the following minsiymposium on multiscale modeling of fracture in quasibrittle solids that will be taking place as part of USNCCM 13 to be held at San Diego [July 26-30]. For those who are interested in submitting an abstract, the deadline is Feb 15th. Please feel free to pass this announcemnts to your colleagues or students whom you think may be interested. We are looking forward to seeing you there either in the audience or giving a talk!

Best Wishes,

Curvature-induced symmetry breaking determines elastic surface patterns

Dr. Emrah Celik is looking for a PhD student with mechanical engineering background (or a related field) who will apply nanotechnology on bio-medical applications. The student will design the mechanical characterization systems, develop computer programs, perform atomic force microscopy (AFM) measurements and analyze data. The ideal candidate will have previous experience or motivation to learn nano-microfabrication, laboratory measurements and finite element analysis. Programming, design and machining experiences are also plus for this position.

G. Ravichandran, J.N. Reddy, and David Srolovitz are among the newly elected members of the US Academy of Engineering.

Introduction

In this minisymposium we seek to highlight challenging problems in computational solid mechanics that require mesh adaptation methods for their solution. We focus on the finite element method and works that address large deformations and the accompanying inelasticity, damage, crack propagation and failure. Discussion will center on Lagrangian descriptions and determining the necessary computational components to resolve, preserve, and evolve the fields that govern these processes. Prototypical material systems may include, but are not limited to, ductile metals and biomaterials.

Our Group of High Performance Materials in Enviormental & Civil Engineering Department at Michigan State University has an openings for PhD positions to work on Multiscale Modeling of Soft Materials starting sSummer  or Fall 2015.
