Prof. Xiaoding Wei's group at the Department of Mechanics and Engineering Science at Peking University (Group Website: https://www.nml-pku.com/) has postdoc openings for graduates with Ph.D. degrees in Applied Physics, Chemical Engineering, Materials Science, and Mechanical Engineering:
A natural impact-resistant bicontinuous composite nanoparticle coating, Huang, et al., Kisailus, Nature Materials, 2020
Novelty/impact/significance:
The rarely known impact surface of the widely reported shrimp dactyl club is a thin, nanoparticle-based coating, possesses both high stiffness and damping properties under high strain rates for exceptional impact resistance, and provides new insights in designing advanced engineered armor materials.
Scientific question:
There are several Immediate Ph.D. positions ( Paid research assistant ) in Energy, control, and Optimization (ECO) lab in the Mechanical Engineering department at Stevens Institute of Technology. The project is related to Renewable energy, radiation Heat transfer, and thin-film solar cells. Being familiar with MATLAB, python, and Optimization algorithms and Machine Learning methods is a Plus.
Journal: International Journal of Fracture
Abstract: A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The kinetic relation for the crack tip velocity given by Linear Elastic Fracture Mechanics (LEFM) is recovered directly from the nonlocal dynamics, this is seen both theoretically and in simulations. An explicit formula for the change of internal energy inside a neighborhood enclosing the crack tip is found for the nonlocal model and applied to LEFM.
Fully funded PhD and Postdoc positions in the area of meta-materials, computational mechanics and wave propagation available in the Department of Mechanical and Nuclear Engineering at Kansas State University. Research will be in topics related to the mechanics of metamaterials and the mechanics of granular media.
Usually, roughness destroys adhesion and this is one of the reasons why the "adhesion paradox", i.e. a "sticky Universe", is not real. However, at least with some special type of roughness, there is even the case of adhesion enhancement, as it was shown clearly by Guduru, who considered the contact between a sphere and a wavy axisymmetric single scale roughness, in the limit of short-range adhesion (JKR limit).
Hello,
Seeking Help: Can anyone share a copy of the following articles: P.C. Bregman, M. Kuipers, H.L.J. Teerling, W.A. van der Veen. Strength and stiffness of a flexible high-pressure spiral hose. Acta Mechanica 97, 185-204 (1993) and B.A. van den Horn & M. Kuipers. Strength and stiffness of a reinforced flexible hose. Applied Scientific Research 45: 251-281 (1988) (which I had and somehow lost).
Thanks in advance
EML Webinar on 9 September 2020 will be given by Prof. Rob Ritchie, University of California, Berkeley, Discussion leader: Nanshu Lu, University of Texas at Austin.
Title: Damage-Tolerance in Engineering and Biological Materials
Time: 7 am California, 10 am Boston, 3 pm London, 10 pm Beijing on 9 September 2020
Structured Materials & Dynamics Laboratory (http://cmdl.missouri.edu/) at University of Missouri develops innovative solutions for Solid Mechanics and Structured Materials, in particular the new frontiers of structural dynamics, wave propagation, micromechanics, topological and quantum mechanics, smart materials and dynamical behaviours of multi-functional materials, both man-made and formed naturally, and understanding relationship between microstructures and material macroscopic properties.
Dear Colleagues, Peers, Friends, and Savants,
Do you want to give back to your community, broaden your research horizons, understand the other side of funding, or just seek a temporary change of venue to reinvigorate yourself? Then, here is an opportunity at NSF/MoMS to do just that: https://beta.nsf.gov/careers/openings/eng/cmmi/cmmi-2020-1826.
Please, consider, disseminate, and encourage worthy candidates. I'm always available to provide more information. You know how to contact me.
