Hybrid fiber-reinforced polymer composites have
extensive applications due to their high strength, corrosion resistance,
low maintenance and design flexibility. However, moisture absorbed by
composite components plays a detrimental role in the integrity and
durability of hybrid structure since it can degrade the mechanical
properties and induce interfacial delamination failures. In the current
study, the moisture diffusion characteristics in two-phase
(unidirectional S-glass fiber reinforced epoxy matrix/unidirectional
graphite fiber reinforced epoxy matrix) hybrid composites using moisture
concentration-dependent diffusion method have been investigated. In the
moisture concentration-dependent diffusion method, the diffusion
Large scale, intricate shape parts with widely varying
cross-sections find difficulty in manufacturing using conventional
manufacturing processes. Cavity molding, a process similar to
compression molding is unique and often used in rotorcraft industries to
manufacture thick flex beam composite parts with high viscosity resins.
The curing of thermosetting resins used in these applications is
usually accompanied by an exothermic reaction and excessive heat buildup
during the polymerization reaction can cause internal stresses to
build-up and result in structural defects in thick composite structures.
Process optimization of flex beam composite parts manufactured using
the cavity molding process will result higher quality parts. In this

Application Deadline: NOON PST 02 December 2013
Recently, I am reading several classic works on crystal plasticity. But, it seems to be difficult for me to obtain several very old papers in this area. For example, one of the classic papers on Hall-Petch relation,
Petch, N.J., The cleavage strength of polycrystals. The Iron and Steel Institute, 1953, 174: 25-28. I have tried many ways to get the original paper, but I finally failed. Could someone please send me a copy of this paper? Thanks a lot. Here is my email: email@example.com
Dear Mechanics Colleagues:
We invite you to submit an abstract to a minisymposium on "Nano and Bio Mechanics" for the 2014 USNCTAM, June 15-20, 2014, to be held at Michigan State University. This minisymposium will focus on the development and application of
both experimental techniques and computational models and methods to
problems of interest in the fields of nano and bio mechanics. Topics of
interest will include, but are not limited to:

Note from the Editor, Kourosh Kayvani:
Title: Electro-Mechanical System Design Intern
Category: Internship in Industry
Employer: Schlumberger Technology Corporation
Location: United States, Texas, Sugar Land
Opening Date: 10/01/2013
I am co-organizing the mini-symposium entitled «Multiscale and multifunctional composites: design and identification» in the 13th International Symposium on Multiscale, Multifunctional and Functionally Graded Materials (MM&FGM2014) with Dr. Gilles Lubineau at King Abdullah University of Science and Technology (KAUST).
The purpose of this mini symposium is to gather leading researchers in the area of multiscale and multifunctional composites to discuss design strategies (both experimental and/or computational) for achieving multifunctional composites materials which have the potential to dramatically improve system-level performance and efficiency.

Scale transition of a higher order plasticity model – a consistent homogenization theory from meso to macroSubmitted by L.H.Poh on Thu, 2013-10-03 00:21.
Standard plasticity models cannot capture the microstructural size effect associated with grain sizes, as well as structural size effects induced by external boundaries and overall gradients. Many higher-order plasticity models introduce a length scale parameter to resolve the latter limitation. This paper adopts two distinct length scales in the formulation, i.e., an intrinsic length scale (l) governing micro-processes such as dislocation pile-up at internal boundaries, as well as the characteristic grain size (L), and aims to unravel the interaction between these two length scales and the characteristic specimen size (H) at the macro level.
A book review by Prof. Jan Achenbach (Northwestern University) is published in the Journal of Applied Mechanics, April, 2014. The book, The Theory of Materials Failure, was authored by Prof. Richard M. Christensen and published by Oxford University Press, 2013.

Post-Doctoral Position: Carbon Nano
Structured Materials: From Characterization & Modeling to Innovative
Product Design (Job Code: ME-PDSK022013)
A postdoctoral research scientist position is available immediately in the Department of Earth and Environmental Engineering at Columbia University. This position is renewable (up to three years) depending on performance. The main responsibility of the project, sponsored by ARPA-E, is to perform computer simulations of crashworthiness of electric vehicles using finite element method. It also involves multiscale modeling of a new type of impact resistant lithium-ion battery, as well as structural design and optimization.
I want to calculate the limit of the fraction (J-1)/(1-2*nu) when material approach to incompressibility, where nu is the Poisson's ratio and J is the third invariant of the Cauchy-Green deformation tensor. In this case J->1 and nu->0.5, but I can't find any reference, how J depends on nu.
Intuitively, this limit has to be a finite value, as it is known that (J-1)^2/(1-2*nu) -> 0 (under the assumption that there is no hydrostatic pressure). Thanks in advance for any suggestions
