Abstract:
Postdoc opportunity at Harvard in mechanics of soft materials for wearable devices
The Wyss Institute for Biologically Inspired Engineering and the School
of Engineering and Applied Science at Harvard University invites
applications for immediate openings for a joint postdoctoral fellow
position between the Whitesides Group (Prof. George Whitesides) and the
Harvard Biodesign Lab (Prof. Conor Walsh). The research is expected to
involve material science and mechanics of soft materials with a focus on
developing novel materials (e.g. actively variable stiffness, flexible
composites, etc) and fabrication approaches for the next generation of

Postdoctoral
Research Associate Position
The
National High Magnetic Field Laboratory (NHMFL) in Tallahassee, FL is seeking a
Postdoctoral Research Associate to work on nanostructured permanent magnets. Preference will be given to candidates who
have a strong commitment to research and development, and can actively contribute
to the programs within the NHMFL.
2013 W. M. Keck Institute for Space Studies Postdoctoral Fellowship Program
Application Deadline: 12 Noon PST 28 November 2012
The W. M. Keck Institute for Space Studies (KISS) at the California Institute
of Technology announces an opportunity for highly qualified individuals to
apply for postdoctoral fellowships to conduct research in space science and
engineering. The primary purpose of KISS is to develop breakthrough planetary,
Earth, and astrophysics space mission concepts and technology by bringing
together a broad spectrum of scientists and engineers for sustained scientific
Reivew of fracture toughness testing and standardization

Effect of Surface Energy on Mechanical Behaviour of Nano Structural Elements
Extremely small size of nano-structures such as beams, sheets and
plates, which are commonly used as components in Nanoelectromechanical Systems
(NEMS), presents a significant challenge to the researchers of nano-mechanics.
Several studies have been developed on the mechanical behavior of nano-sized
bars, tubes, sheets and plates. The results of these studies show that the
elastic modulii of such nano-structural elements depend on their size.
Unfortunately, classical elasticity lacks an intrinsic length scale and thus
Elastic-plastic analysis
Hello Everyone,
I am a beginer in using Abaqus. I am going to model a nothed specimen subjected to cyclic loads, to investigate the stress/strain distribution and so on. I would appreciate if you guide me.
HELP : Modal Analysis of Piezoelectric UEL Element
Hello Experts,
I am trying to do modal analysis on user-defined piezoelectric shell element. My eigen value probelm of free vibration is given in the attachment.
