We have an immediate opening in the Department of Engineering Science and Mechanics for a postdoctoral research associate in multiscale modeling and computational mechanics. The focus of this position is on the modeling, simulation, and analysis of the nonlinear evolution of coupled macro/microstructure in failure processes, with an emphasis toward structural health monitoring. Coupled-field models using continuum damage variables will be used to study the fundamental spatiotemporal features of damage evolution, particularly regarding the nature and origin of unpredictability in damage processes. The candidate must have a solid general background in theoretical mechanics and dynamics, and be familiar with nonlinear finite element analysis
The person in this position will be responsible for developing finite element-based soft tissue representations that supportreal-time interaction with surgical tools. The successful candidate should befamiliar with the extensive prior work in the field of surgical simulationincluding finite element formulations (both traditional nonlinear approaches aswell as various real-time approximations), real-time collision detection andresponse between rigid and deformable objects, multi-processor/coreimplementations, and integration with haptics devices.
In classical elasticity, we know that at the interface of two different materials, traction stresses and non-traction strains are cotinuous. Traction stresss are continuous according to Newton's third law, but why non-traction strains are continuous?
The symposium "Current Issues in Polymer Nanocomposites" is being organized for the 2008 ASME IMECE Conference to be held at the Hynes Convention Center in Boston, MA from October 31 - November 6. The symposium is Track 13-11 [corrected track number] and is co-sponsored by the Materials Division of ASME.General topics of interest for the symposium may include, but are not limited to:
* Consistency between experimental and computational studies on nanocomposites
A symposium on "Defects in materials: Theory and Applications" is being organized at the 2008 ASME conference in Boston (Oct 31-Nov6). To submitt abstracts to this symposium choose Track 12-4 (Track 12, topic 4). The abstract submission deadline is March 3, 2008. Below is the description and scope of the symposium:
The preprint provides the summary and/or review of current state-of-art in coarse-grained modeling of protein structures for normal mode analysis. This review summarizes the quasiharmonic analysis, Go model, elastic network model, and recently suggested coarse-grained models for protein structures.
I would like to know which software is people using for meshfree simulation. Is there any more or less "standard" one that people tend to use? I'm interested in knowing about any one for any kind of problem.
A post-doc position is available at the University of Notre Dame in Aerospace and Mechanical Engineering. The project focuses on nanocomposite deformation modeling and performing corresponding experiments using primarily atomic force microscope and X-ray diffractometer. Initial position is for one-year and is extensible for another year contingent upon continued funding. The position offers attractive collaborative opportunities with national labs and material synthesis groups across different universities. Salary is negotiable.
A postdoc position is available immediately in the School of Mechanical Engineering at Gerogia Tech. Interested persons with atomistic/molecular level simulation of metal/polymer interfaces are invited to contact Jianmin Qu at email@example.com
I am looking for two postdocs in the analytical and computational modeling areas. One position will focus on the theoretical and computational modeling of microstructure-modulated failure processes, with an emphasis on nanocrystalline materials. The other will focus on hypervelocity impact fragmentation problems, including planetary scale impact and fragmentation. The latter position is available immediately, and the former is available as of June 1, 2008.

Evolving from earlier meetings on erosion, the International Conference on Liquid and Solid Impact (ELSI-IX) and the International Conference on Erosive and Abrasive Wear (ICEAW-II), the 1st International Conference on Abrasive Processes (ICAP-I) will be held in the historic city of Cambridge, England, 21-25 September 2008.
I'm using ANSYS for study the internal stresses of a trilayer structure resulting after a cooling process. The middle layer (the solder) has temperature dependent material properties and the other two layers can be considered temperature indipendent mat. properties. If I use a static analysis the software uses the material properties reffered to final temperature.
For an linear elastic analysis is this a realistic procedure?
If the solder deforms plastically at high temperature and not at final temperature..how can I do?
Now i'm working on biomechanics research project which deals with the articulating surface of joint replacement, where one of the main problem were the wear of sliding contact (i.e., metal on polymer,metal on metal or polymer on ceramics).wear debris or particles generated from this articulating surface can causes the damage of the bone cell around the joint replacement.My question are;
