Minutes of iMechanica get-together at McMat 2007

On 6 June 2007, about 50 mechanicians attended a special session at the McMat 2007, " get together". The attendees of this special session came from various job sectors, such as academia, industry as well as government agencies. The session was chaired by K. Ravi-Chander and Rui Huang, who also served in the organizing committee of McMat 2007.

Biot Medal to Dr. James R. Rice

Biot Medal The 2007 Maurice A. Biot Medal for Poromechanics has been awarded during the ASCE Engineering Mechanics Conference held at Virginia Tech last Tuesday.

The 2007 Biot Medal winner is Dr. James R. Rice of Harvard University.

If you are interested in further information, such as citation of Dr. Rice's work, and photos, you can check this page:

Mechanical Threshold Stress model for 6061-T6 aluminum alloy

I have attached a copy of my McMat07 talk below.  The talk is about a modified mechanical threshold stress (Follansbee-Kocks) model that can be used for strain rates > 1000 /s and high homologous temperatures.  In the model, the pressure dependence of the flow stress arises from the pressure dependence of the shear modulus.  Even after using the most accurate models for the shear modulus (and the melting temperature) we find that the pressure sensitivity of the flow stress is underestimated by our model (by quite a bit).

An e-book on engineering fracture mechanics

Here is an e-book on Engineering Fracture Mechanics ; you can also download a demo version, the preface, and other related stuff from the page. The idea of the book (as described in the page) sounds interesting:

International Journal of Solids and Structures (IJSS) will be freely accessible

At a meeting of the Editorial Board of IJSS, on Sunday, 3 June 2007, in Austin, Texas, the representatives from Elsevier, the publisher of IJSS, told the members of the Board that all articles published in IJSS will be freely accessible 24 months after publication.  The first of these articles will become available in October 2007.  That is, all IJSS articles published after October 2005 will become freely accessible after a delay of 24 months.

Comparative Computational Mechanics / Engineering Science

If you had to design a course of the title: "Comparative Computational Mechanics" or "Comparative Methods of Computational Engineering Science and/or Mechanics", what would its contents be like?

A postdoc position in computational mechanics

A postdoc position in computational mechanics/mathematics is available at Department of civil, environmental and ocean engineering, Stevens Institute of Technology. The candidate will participate in a pioneering research work on multiscale stochastic modeling sponsored by US Department of Energy. His/Her work will also be involved with collaborative research at Los Alamos National Laboratory. Experience on multiscale methods, high performance/parallel computing, or computational fracture/damage modeling is desired. Please contact:      

Peridynamic theory vs. classical continuum theory

Dr. Stewart Silling has provided me with a copy of his talk on Peridynamic theory that he presented at McMat 2007.  The PDF file of the talk is attached below.

In order to deal with classical material models and volume constraints, Dr. Silling has modified the original theory to allow for forces that are not necessarily pairwise. A bit on that is included in the talk.

Call for Papers: Multiscale Modeling and Simulation: from Molecules to Cells to Organisms

Dear Colleague,

We want to draw your attention to and encourage your participation in a special session on Multiscale Modeling and Simulation of the thirteenth Pacific Symposium on Biocomputing (PSB), to be held January 4-8, 2008, on the Big Island of Hawaii. PSB is an international, multidisciplinary conference with high impact on the theory and application of computational methods in problems of biological significance.

Anharmonic lattice statics analysis of 180^o and 90^o ferroelectric domain walls in PbTiO3

This paper presents an anharmonic lattice statics analysis of 180 and 90 domain walls in tetragonal ferroelectric perovskites. We present all the calculations and numerical examples for the technologically important ferroelectric material PbTiO3. We use shell potentials that are fitted to quantum mechanics calculations. Our formulation places no restrictions on the range of the interactions. This formulation of lattice statics is inhomogeneous and accounts for the variation of the force constants near defects.

Study of the simple extension tear test sample for rubber with Configurational Mechanics

The simple extension tear test-piece also referred to as the trousers sample is widely used to study crack propagation in rubber. The corresponding energy release rate, called tearing energy for rubber materials, was first established by Rivlin and Thomas (Rupture of rubber. I. Characteristic energy for tearing. J. Polym. Sci., 10:291–318, 1953); a second derivation was proposed later by Eshelby (The calculation of energy release rates. In G. C. Sih, H. C. van Elst, and D. Broek, editors, Prospects of Fracture Mechanics, 69–84, Leyden, Noordhoff, 1975).

Bi-functional optimization of actively cooled, pressurized hollow sandwich cylinders with prismatic cores

All metallic, hollow sandwich cylinders having ultralight two-dimensional prismatic cores are optimally designed for maximum thermo-mechanical performance at minimum mass. The heated cylinder is subjected to uniform internal pressure and actively cooled by forced air convection. The use of two different core topologies is exploited: square- and triangular-celled cores. The minimum mass design model is so defined that three failure modes are prevented: facesheet yielding, core member yielding, and core member buckling.

An old and unfunded proposal to NSF to create iMechanica

In response to a NSF call for proposal on Cyberinfrastructure Training, Education, Advancement, and Mentoring for Our 21st Century Workforce (CI-TEAM), in June 2006, several of us submitted a proposal entitled "iMechanica:  Leveraging Cyberinfrastructure to Evolve All Knowledge of Applied Mechanics"

Nanomechanics and Nanostructured Multifunctional Materials: Experiments, Theories, and Simulations

Dr. Jun Lou and Dr. Junlan Wang are co-editing a special issue on Nanomechanics and Nanostructured Multifunctional Materials: Experiments, Theories, and Simulations for Journal of Nanomaterials, an open access journal. Papers on latest developments on all aspects of nanomechanics and nanostructured materials are welcome. Deadline for manuscript submission is September 01, 2007.

Why not use FDM in solid mechanics?

Finite Difference Method (FDM) and the related techniques such as FVM, are often found put to great use in fluid mechanics. See any simulation showing not only streamlines but also vortex shedding, turbulent mixing, etc.
