Post-doctoral position - Stochastic computational techniques to deal with uncertainties on the geometry in structural analysis

The post-doctoral student will join the pole "Structures and Couplings" of the Research Institute en Civil Engineering and Mechanics (GeM), Nantes, France (Nantes University, Ecole Centrale Nantes, CNRS UMR 6183)

We have recently been awarded a Research Project by the French National Research Agency. This project addresses theorical and numerical developments in the field of stochastic computational mechanics. The main goal of this project is to develop a robust computational technique to deal with uncertainties on the geometry in structural analysis. The proposed methodology lies on the extension of the Extended Finite Element Method (X-FEM) into the stochastic framework and the development of efficient computational techniques for solving stochastic systems.

A field of material particles vs. a field of markers

In continuum mechanics, it is a common practice to view a body as a field of material particles, so that the continuum mechanics is phrased as an algorithm to determine the function x(X, t), where X is the name of a particle, and x is the place of the particle at time t.

Deformation of FCC Nanowires by Twinning and Slip

We present atomistic simulations of the tensile and compressive loading of single crystal FCC nanowires with <100> and <110> orientations to study the propensity of the nanowires to deform via twinning or slip.  By studying the deformation characteristics of three FCC materials with disparate stacking fault energies (gold, copper and nickel), we find that the deformation mechanisms in

A Discussion on Time Integrators

Hi to all :

This is my first blog entry . And I have only recently started my Research work (just 2 months) .So please bear with me my lack of thorough knowledge in the topic .

What I want to know is "what is the impact of the papers on Asynchronous Variational Integrators and Variational Integrators (published in 2003) ?" I mean what I was wondering is given that they have so many beneficial properties , how many researcher have actually started using this technique of time integration in their research .

Notes on Nonlinear Fracture Mechanics

These are the notes I wrote at the Technical University of Denmark in 1979. Zhigang Suo and I will be using these in the course on fracture and thin film mechanics (ES 242r) this spring (2007). This is a joint course with the University of Nebraska.

Flip test: imagine continuum mechanics as a revolutionary idea

Let's say the world has only e-books, then someone introduces this technology called 'paper.' It's cheap, portable, lasts essentially forever, and requires no batteries. You can't write over it once it's been written on, but you buy more very cheaply. Wouldn't that technology come to dominate the market?

Symposium on "Mechanics of Nanofabrication and Nanostructure Growth" at the 2007 IMECE (ASME Meeting)

(Please also refer to node/711 for the introduction of this ASME meeting and some important changes. )

Mechanics has been playing a critical role in understanding the fabrication and reliability of nanostructured material systems, such as the self-assembly of quantum dots during heteroepitaxial thin film growth. Sponsored by the Elasticity Committee of Applied Mechanics Division, this symposium will identify opportunities and challenges in mechanics of materials that are motivated from a variety of novel and emerging nanofabrication and nanostructure growth methods. Presentations in experimental, theoretical, and computational studies are solicited in the following areas (but not limited to):

A subdomain collocation method based on Voronoi domain partition and reproducing kernel approximation

A subdomain collocation method based on Voronoi diagrams and reproducing kernel approximation is presented. The unkonwn field variables are approximated via reproducing kernel approximation. The body integration arising from the numerical evaluation of Galerkin weak form is converted into much cheaper contour integration along the boundary of each Voronoi cell. The Voronoi cells also provide an natural structure to perform h-adaptivity.

A short paper on T-stress of an interfacial crack in a bi-material strip

The attached file is on T-stress of an interfacial crack in a bi-material strip. The geometry of the problem is the same with that of Suo and Hutchinson (1990, IJF). Using a conservation integral technique, a formula for T-stress is derived with two numerical factors.

Interfacial Thermal Stresses in a Bi-Material Assembly with a Low-Yield-Stress Bonding Layer

An approximate predictive model is developed for the evaluation of the interfacial thermal stresses in a soldered bi-material assembly with a low-yield-stress bonding material. This material is considered linearly elastic at the strain level below the yield point and ideally plastic at the higher strains. The results of the analysis can be used for the assessment of the thermally induced stresses

PhD Studentship - Imperial College London

An EPSRC-funded PhD Studentship is available in the Mechanics of Materials Group, Department of Mechanical Engineering at Imperial College London in the general area of theoretical/computational solid mechanics. Funding comes in the form of an EPSRC award (DTA scheme), and as such there is much flexibility in the project scope. A few tentative possibilities are: discrete dislocation modeling of high-temperature creep in dispersion-strengthened superalloys, crack nucleation criteria for functionally graded materials, fracture and post-operative remodeling of trabecular bone (jointly with the biomechanics group).

On the thermomechanical coupling of shape memory alloys and shape memory alloys composites

Smart materials have received much attention in recent years, especially due to their various applications in smart structures, medical devices, actuators, space and aeronautics. Among these
materials, shape memory alloys exhibit extremely large, inelastic, recoverable strains (of the order of 10%), resulting from transformation between austenitic and martensitic phases. This
transformation may be induced by a change, either in the applied stress, the temperature, or both.

Symposium "Multiphysics behaviors of materials at the nanoscale" at USNCCM-09

The mechanical, thermal, electrical, and chemical behaviors of nanostructured materials such as nanocrystalline materials, nanowires, nanofilms, and nanotubes have been increasingly studied with advanced simulation techniques such as the molecular dynamics (MD) method and its various variants including the Car-Parrinello method, Monte Carlo method, the tight-binding MD method, and first principle methods. However, quite often the analyses neglect the correlations among the different types of behaviors of the materials. Characterization of such correlations necessitates multiphysics approaches in modeling, simulation, and experiments. Examples include fatigue of nanocrystalline materials in corrosive environments, piezoelectric behavior of nanowires, and thermal-mechanical coupling of the behavior of nanobelts. With advances in the development of nanomaterials, there is a strong need to quantify material behavior accounting for multiphysics processes in a coupled manner. This symposium is intended to bring together researchers in multiphysics modeling, simulation and experiments of nanomaterials and nanostructured materials. The focus is primarily on a survey of the state of the art in molecular level multiphysics modeling, simulation, and experiments. Presentations on method development, behavior characterization, atomistic description, and continuum representation are all strongly encouraged.  (USNCCM website)

Adaptation of arteries to pressure changes

Arteries are living organs that can remodel themself in response to stress changes. Arterial remodeling is a big topic and this paper shows only a tip of the iceberg.
