The velocities of atoms in MD simulation are not objective quantities, which depend on the choice of the reference frame and sample size. In our previous study (http://imechanica.org/node/3181), we discussed how to overcome this non-objectivity and compute the atomic stress objectively. In this blog, our newly published paper on temperature computation is attached, and the abstract is as follows.

PhD and Post-Doc positions are now available at the Institut für Angewandte Mechanik of the Technische Universität Braunschweig, Germany. Both are full-time fixed-term positions for 2 years with the possibility of renewal.

Dear Colleagues

The SES 50th Annual Technical Meeting will be held July 28-31, 2013 at Brown University (Providence, RI, USA).
I would like to invite you to submit an abstract to the symposium: "Experimental Nanobiomechanics", under Mechanics of Biological and Soft materials.

This symposium covers experimental methods in biomechanics with an emphasis on nanoscale and microscale biomechanics. Methods include but not limited to atomic force microscopy for imaging and characterization, bio-MEMS for biomechanical characterization of cells and biomaterials, microfluidic application in medicine and biology, and similar methods. Methods covering multiple scales are particularly emphasized.

Academic posts (Lecturer/Senior Lecturer/Reader/Professor) in Computational Mechanics(including Fracture Mechanics, Inelasticity and Geomechanics) Durham University, UK

Up to four posts are available to join an existing team including a number of recent young hires (Akkerman, Koziara, Coombs, Giani, Mao, Gonnet ... ) in a general engineering school which also includes computer science. We are now one of the largest groups in computational mechanics in the UK.

In this paper, we present a geometric discretization scheme for incompressible linearized elasticity. We use ideas from discrete exterior calculus (DEC) to write the action for a discretized elastic body modeled by a simplicial complex. After characterizing the configuration manifold of volume-preserving discrete deformations, we use Hamilton's principle on this configuration manifold. The discrete Euler-Lagrange equations are obtained without using Lagrange multipliers. The main difference between our approach and the mixed finite element formulations is that we simultaneously use three different discrete spaces for the displacement field.

Due to a large number of requests, the deadline to submit an abstract to the 12th US National Congress on Computational Mechanics, to be held in Raleigh this summer, has been extended to March 15, 2013. Students and postdoctoral fellows should note that there are travel awards  available for the Congress.

Description

New Technologies Research centre at the University of West Bohemia
(Czech Republic) invites applications for a Postdoctoral position in the
field of Computacional Mechanics of Materials. Highly motivated
individuals holding a PhD in Mechanics, Materials Science or closely
related fields are encouraged to apply.

We welcome applications for a fully funded PhD position in the field of experimental mechanics and materials science. Further details in the attachment.

AmeriMech symposia are intended to promote interactions among researchers in an area of contemporary interest in the mechanics of fluids and solids. It is expected that the symposia will address topics of a specialized nature, will be small in size (about 50 participants) with minimal cost, held in an informal setting, encourage participation of young researchers, and promote interdisciplinary ideas and discussions. This format allows for in-depth discussions and close interactions between participants. Such symposia are known to help assess the state-of-the-art and chart new directions for the future.

Several recent papers have reported measurements of adhesion energy between graphene and other materials (e.g., Si/SiOx and copper) [1-3]. Like thin films, many experimental methods may be adopted to measure the interfacial properties of graphene, such as the pressurized blister test [2] and the double-cantilever beam test [3]. The challenges lie in the handling of atomically thin membranes and analysis/interpretation of the data.

The Atomistic Materials Modeling group of Prof. Erik Bitzek is
inviting applications for doctoral students in the area of Computational
Materials Science to join the Institute for General Materials Properties within
the Department of Materials Science of the Friedrich-Alexander-Universität
Erlangen-Nürnberg in Erlangen, Germany.

Research topics
include:

 A postdoctoral position with primary focus on molecular dynamics simulations is available immediately at Shenoy Research Group  under the direction of Prof. Vivek B. Shenoy .  We are looking for a strongly motivated candidate to work on modeling of nanomaterials and soft materials. The ideal candidate will have a background in materials science/computational physics with expertise in molecular dynamics simulations with LAMMPS or other packages.  This individual will have the opportunity to be directly involved in complimentary experimental investigations, both at Penn and our collaborators in industry. 

One Ph.D. position is now available starting October 2013 on magnetorheological elastomers in the Solid Mechanics Laboratory of Ecole Polytechnique, France. The potential student will work on the development of new experimental procedures and high fidelity numerical models for the understanding and constitutive description of microstructured magnetorheological solids. Students with strong interest in new coupled problems and strong background in engineering, physics or/and mechanics are encouraged to apply.
