Dear all,

I just joined this group last week. And, I'd like to share some of reading material that I found regarding research directions in computational mechanics. The paper was published in 2003, written by Tinsley Oden, Belytschko, Babuska and Hughes. It's entitled "Research Directions in Computational Mechanics" (Computer Methods in Applied Mechanics and Engineering, 192, pp 913-922, 2003). They outlined six areas with significant research opportunities in CM:

"Persistence of a pinch in a pipe" by L. Mahadevan, Ashkan Vaziri and Moumita Das

The response of low-dimensional solid objects combines geometry and physics in unusual ways, exemplified in structures of great utility such as a thin-walled tube that is ubiquitous in nature and technology.

regarding time integrators : AVI vs Subcycling

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 .

What is Grid Computing? How can it be important to mechanicians? When?

At the suggestion of Joy Sircar, the Chief Technology Officer at the School of Engineering and Applied Sciences, of Harvard University, iMechanica has just added a forum called Technology Corner. As Joy has framed it, this new forum intends to host conversations on software and hardware technologies that might be relevant to mechanicians.

Here is a question I have. Lately I've heard the phrase Grid Computing a number of times. It is about networking lots of computers and other electronic devices, and supply users with computing power like supplying electricity. That is, computing power will become a utility. One might even hope software will also become utilities. Some people say that Grid Computing will happen in just a few years, or may be already here. Here is a collection of essays in Nature on 2020 Future of Computing.

THE MOST CITED SCIENTIFIC PAPERS IN SOLID AND COMPUTATIONAL MECHANICS

I posted this survey in Applied Mechanics Research and Researchers on 16 April 2006, based on a survey of Web of Science. A paper making the list satisfied the following conditions:

  • It is in the areas of solid mechanics, mechanics of materials, or computational mechanics, and
  • It has at least 1000 citations.

This list may not be complete. If anyone finds a missing entry, please leave a comment below.

The cited number has been updated up to 18 Dec. 2006.

Mechanics and deformation of the nucleus in micropipette aspiration experiment

Robust biomechanical models are essential for studying the nuclear mechanics and can help shed light on the underlying mechanisms of stress transition in nuclear elements. Here, we develop a computational model for an isolated nucleus undergoing micropipette aspiration. Our model includes distinct components representing the nucleoplasm and the nuclear envelope. The nuclear envelope itself comprises three layers: inner and outer nuclear membranes and one thicker layer representing the nuclear lamina.

A mini-symposium on

COMPUTATIONAL METHODS FOR MICRO AND NANO SYSTEMS

Call for Papers
Micro and Nano Electro Mechanical Systems have recently attracted much attention from the industry and from the scientific community. MEMS are nowadays routinely met in various fields like in the automotive, aerospace and large consumer applications.
It can be said that for various micro systems the pioneering phase has been substituted by a phase of industrial applications. Hence, new challenges concerning reliability, optimization and increasing miniaturizations must be tackled by the designers. All these issues need a multi-disciplinary approach and must be supported by multi-physics numerical and experimental analyses able to contribute to the definition of a unified design and analysis methodology of MEMS and NEMS.

Metallic sandwich plates subject to intense air shocks (by Ashkan Vaziri and John W. Hutchinson)

Recent results on fluid-structure interaction for plates subject to high intensity air shocks are employed to assess the performance of all-metal sandwich plates compared to monolithic solid plates of the same material and mass per area. For a planar shock wave striking the plate, the new results enable the structural analysis to be decoupled from an analysis of shock propagation in the air. The study complements prior work on the role of fluid-structure interaction in the design and assessment of sandwich plates subject to water shocks. Square honeycomb and folded plate core topologies are considered. Fluid-structure interaction enhances the performance of sandwich plates relative to solid plates under intense air shocks, but not as significantly as for water blasts. The paper investigates two methods for applying the loading to the sandwich plate-responses are contrasted for loads applied as a time-dependent pressure history versus imposition of an initial velocity.

Deformation of the cell nucleus under indentation: Mechanics and Mechanisms

Computational models of the cell nucleus, along with experimental observations, can help in understanding the biomechanics of force-induced nuclear deformation and mechanisms of stress transition throughout the nucleus. Here, we develop a computational model for an isolated nucleus undergoing indentation, which includes separate components representing the nucleoplasm and the nuclear envelope. The nuclear envelope itself is composed of three separate layers: two thin elastic layers representing the inner and outer nuclear membranes and one thicker layer representing the nuclear lamina. The proposed model is capable of separating the structural role of major nuclear components in the force-induced biological response of the nucleus (and ultimately the cell). A systematic analysis is carried out to explore the role of major individual nuclear elements, namely inner and outer membranes, nuclear lamina, and nucleoplasm, as well as the loading and experimental factors such as indentation rate and probe angle, on the biomechanical response of an isolated nucleus in atomic force microscopy indentation experiment.

Mini-symposium on “Computational Methods in Impact Engineering” in Ninth U.S. National Congress on Computational Mechanics

The aim of the “Computational Methods in Impact Engineering” mini-symposium is to recognize the increasing role of the computation methods in Impact Engineering. It is now established that computational tools are indispensable to augment experimental techniques for the analysis of complex systems under dynamic loading. Many new computational techniques are currently being developed and new applications in the fields of impact and shock loadings are emerging. This mini-symposium will bring together engineers and scientists working in the area of Computational Impact Engineering.

Topics of interest include (but are not restricted to) the following:

Ninth U.S. National Congress on Computational Mechanics

USNCCM IX, July 22 - 26, 2007
Pre- & Post-Congress Short Courses, July 22 & 26, 2007
Hyatt Regency San Francisco
San Francisco, California

BACKGROUND AND SCOPE
From their inception in 1991, the biennial congresses of the United States Association for Computational Mechanics have become major scientific events, drawing computational engineers and scientists worldwide from government, academia, and industry. The Ninth U.S. National Congress on Computational Mechanics (USNCCM IX), hosted by the University of California, Berkeley, will feature the latest developments in all aspects of computational mechanics, and will broaden the definition of the discipline to include many other computation-oriented areas in engineering and sciences. From applications in nanotechnology and bioengineering, to recent advances in numerical methods and high-performance computing, the technical program will reflect the Congress theme of "Interdisciplinary Computation''. In addition to plenary lectures and minisymposia that highlight the latest trends in computational mechanics, pre- and post-conference short courses addressing advances in multiscale and multiphysics methods, as well as other topics, will be held. Numerous vendor exhibits from Bay Area and national companies and organizations are also planned. Detailed information on USNCCM IX can be found at:
