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.

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.

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.

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.

Influence of depolarization field on polarization states in epitaxial ferroelectric thin films with biaxial misfit strains

Depolarization field and misfit strain are two important factors that may greatly influence the properties of ferroelectric thin films. The effect of depolarization field on polarization states of single-domain ferroelectric thin films with nonequally biaxial in-plane misfit strains are studied in the present work by numerically solving three coupled Euler-Lagrange equations, which are derived from the minimization of total free energy.

Biomolecular detection by a cantilever functionalized by RNA aptamers as receptor molecules

We have recently reported the label-free detection of HCV (Hepatitis C Virus) helicase by using a resonating microcantilever whose surface is functionalized by RNA aptamers as receptor molecules. This work was accepted for publication at Biosensors & Bioelectronics.

Kinetics of phase transformations in the peridynamic formulation of continuum mechanics

Abstract 

We study the kinetics of phase transformations in solids using the peridynamic formulation of continuum mechanics. The peridynamic theory is a nonlocal formulation that does not involve spatial derivatives, and is a powerful tool to study defects such as cracks and interfaces.
