Shock attenuation is of prime concerns when bodily organs are involved, such as traumatic brain injury. Most armor systems nowadays are aimed at defeating the threat, such as breaking a projectile using hard ceramic armor. Yet, such solutions do not mitigate the initial acceleration (elastic) wave that is responsible for internal organ damage, although no penetration occurred.
Dear iMechanicians,
Please find below a paper, co-authored with Ivan Cuesta and Norman Fleck, on the mode II fracture of elastic-plastic sandwich layers. The paper is part of the special issue in the Journal of Applied Mechanics dedicated to John Hutchinson's 80th anniversary and the Century Fracture Mechanics Summit.
Hi
I am sharing this position on behalf of Prof. Tim Dodwell, University of Exeter:
The position is a 2-year postdoctoral research fellowship within the Institute of Data Science and Artificial Intelligence at the University of Exeter. The role will work with Turing AI Fellow Prof Tim Dodwell .
Summary of the role
"Soft magnetoactive laminates: large deformations, transverse elastic waves and band gaps tunability by a magnetic field" by N. Karami Mohammadi et al (2019) has been published in November Special Issue in Journal of Applied Mechanics.
This paper is part of my group and co-author work on the topic of Soft Magneto-Active Composites:
Abstract: Even for relatively simple thin shell morphologies, many different buckled configurations can be stable simultaneously. Which state is observed in practice is highly sensitive to both environmental perturbations and shell imperfections. The complexity and unpredictability of postbuckling responses has therefore raised great challenges to emerging technologies exploiting buckling transitions.
The M&S Lab in Department of Mechanical Engineering, Kyung Hee University (South Korea) is recruiting highly motivated a postdoctoral researcher (starting 2020 summer) and a Ph.D student (starting 2020 September). The candidate is expected to be highly self-motivated, independent, and high-level coding skill (For examples, Fortran, JAVA, C/C++, Python, matlab, etc). Excellent publication record additionally requires to the postdoctoral research position.
Dear Colleague,
It is well known that the straight configuration of a flexible vertical riser conveying fluid destabilizes in a divergence-type buckling instability once the velocity of the transporting fluid exceeds a critical speed. To compute the critical velocity, the dynamics of small amplitude perturbations to the straight configuration are computed. If the perturbations are sufficiently small and the transport speed is above a critical value, then the instability of the vertical riser can be detected.
Dear Colleague,
I'm delighted to inform you that the Department of Mechanical Engineering University of California, Berkeley, seeks candidates for a tenure-track faculty position at the Assistant Professor level, starting July 1, 2020 or on a mutually agreed date thereafter. The department seeks candidates with expertise in one or more of the following: Fluid Mechanics; Energy Science and Technology; Design and Manufacturing; and Control and Robotics.
