Vicky Nguyen, of the Johns Hopkins University, is named Editor of the iMechanica Journal Club. Vicky has a broad vision for mechanics, and has made contributions to diverse topics. in 2008, she received the Presidential Early Career Award for Scientists and Engineers. In 2013, she received the Sia Nemat-Nasser Early Career Award and the Eshelby Mechanics Award for Young Faculty.
The mission of the Journal Club is to facilitate discussion at the frontier of mechanics and its applications.
To enable the discussion, each month an Editor selects a Discussion Leader, who in turn posts a Theme. The Theme stays at the top of the front page of iMechanica for the entire month. See Recent and Past Themes, and the Operating Notes for the Journal Club.
Vicky will share the responsibility of editing the Journal Club with Xuanhe Zhao. Feel free to contact either of them if you have an idea for a theme, or if you would like to volunteer a colleague.

The reaction of Zr/B multilayers with a 50 nm modulation period has been studied using scanning AC nanocalorimetry at a heating rate of approximately 1,000 K/s. We describe a data reduction algorithm to determine the rate of heat released from the multilayer. Two different exothermic peaks are identified in the nanocalorimetry signal: a shallow peak at low temperature (200 - 650°C) and a sharp peak at elevated temperature (650 - 800°C). TEM observation shows that the first peak corresponds to heterogeneous inter-diffusion and amorphization of Zr and B, while the second peak is due to the crystallization of the amorphous Zr/B alloy to form ZrB2.

Applied Mechanics Division Honors & Awards Banquet, 19 November 2013, Manchester Grand Hyatt, San Diego.
Thank you to all of you for this fine honor.
For sure I have been around a long time and I have seen it all, so I’ll give you some impressions of what I have observed over the long haul in the world of applied mechanics. Let me start by mentioning that I have a technical paper coming out in Journal of Applied Mechanics in the January 2014 issue. This was kindly facilitated by the technical editor, Yonggang Huang. If you wish, please consider that as my formal speech, but no one wants to hear about equations tonight.
Instead I’ll talk a little about technical generations. Each generation has its own character and its own challenges. What is a generation if not a collection of workers, individuals. So this is really about individuals. It’s not so much about exactly what each of them did, but more about the how and the why they did what they did. What was their propulsion system, their energy source?

Dear Mechanics Colleagues:
A pleasant reminder that 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:
Post-Doctoral Position in Micro-scale Testing and Characterization of Metals at Johns Hopkins UniversitySubmitted by jelawady on Wed, 2013-11-20 13:40.
We are soliciting applications from outstanding candidates for a postdoctoral
research position in the Computational & Experimental Materials Engineering
Laboratory, at the Department of Mechanical Engineering, Johns Hopkins
University starting immediately. This will be a one year position renewable
depending on performance.
In this paper, the mechanical behavior of freestanding thin sputter-deposited films of Au is studied at temperatures up to 340°C using tensile testing. Films tested at elevated temperatures exhibit a significant decrease in flow stress and stiffness. Furthermore the flow stress decreases with decreasing film thickness, contravening the usual notion that “smaller is stronger”. This behavior is attributed mainly to diffusion-facilitated grain boundary sliding.
This paper has been accepted by Scripta Materialia.
The group of Advanced Materials and Dynamics Lab at the University of Arkansas at Little Rock has one opening for a Ph.D. student in the field of mechanics of materials. The appointment is starting on May 2014 or August 2014.
Consider the set of monic fourth-order real polynomials transformed so that the constant term is one. In the three-dimensional space of the coefficients describing this set, the domain of asymptotic stability is bounded by a surface with the Whitney umbrella singularity. The maximum of the real parts of the roots of these polynomials is globally minimized at the Swallowtail singular point of the discriminant surface of the set corresponding to a negative real root of multiplicity four.
Calorimetry is a widely used technique to study the thermal properties of materials including heat capacity, temperature and enthalpy of transformation/chemical reaction. In a typical calorimetry mesurement, a controlled power is supplied to the material to heat it up, and the resulting temperature as a function of time is recorded.
The selling point of scanning AC calorimetry is that it enables accurate nanocalorimetry measurements at a wide range of scanning rate (-2e3 K/s to 2e3 K/s) as well as temperature (currently up to 1000 C, limited by the calorimetry device). Such range (scanning rate < 1e3 and temperature > 500 C) is hard to be accessed by DC calorimetry due to the increasing effect of heat loss from sample to the environment.
these papers might interest those engaged in the assessment of the mechanical properties of nanocomposites using multiscale approaches.
Enthusiastic and highly motivated postdoctoral scientists are sought to work on 3D printing/additive manufacturing at Singapore.
The candidates should have rich experiences in relevant research areas, good publication records, and excellent writing skills.
Preference will be given to those with experience in (1) molecular dynamics modeling or (2) manufacturing. The contract will be one year and renewable subject to performance.
The Dept of Eng Sci at Uppsala University is looking for a project worker in structural modeling of the 17th century Vasa ShipSubmitted by syvoney on Tue, 2013-11-19 11:32.
17th century Vasa ship is unique in its kind and of high cultural
and historical interest. Therefore, interdisciplinary research teams are
constantly busy to keep the slowly degrading and deforming warship in good
geometrical shape. Initiated in 2012, the latest research project aims to
investigate creep in the Vasa ship and to develop a new support system for
improved dimensional stability. For this purpose a finite element model will be
created to assess the effect of varying geometrical parameters and material
properties. One of the key aspects is the influence of the joints of the ship
This paper might interest those engaged in the assessment of non-linear notch root stresses and strains. Please take a look, the paper is free.
