Maybe because I am proud of Betti's theorem being italian, I am curious about this big emphasys on systems violating it. They may "open avenues for energy absorption, conversion and harvesting, soft robotics, prosthetics and optomechanics".... ? I'd be curious to hear some comments. Anyway, the last author Andrea Alu is anyway italian like Betti.
A funded PhD position is open for summer or fall 2017 in the Mechanics and Dynamics Laboratory in the Department of Aerospace Engineering at Wichita State University. The research program will focus on the design and development of mechanical metamaterials, their application towards aerospace structures, and will involve a combination of analytical, numerical, and experimental methods. The candidate must have a MS in Aerospace or Mechanical Engineering and a strong background in structural mechanics and dynamics.
We would like to invite you to submit an abstract to the symposium F-3: Wave Phenomena in Linear and Nonlinear Metamaterials at the SES 53rd Annual Technical Meeting (SES2016) to be held October 2-5 2016 in College Park, MD.
In this paper we propose different classes of isotropic microstructured media with tunable Poisson's ratio. The elastic periodic systems are continuous porous media and two- and three-dimensional lattices. The microstructural parameters can be tuned in order to have an effective Poisson's ratio equal to zero. The connection between microstructural parameters and effective properties is shown in detail both analytically and numerically.
This paper proposes the design of a two-dimensional porous solid with omnidirectional negative Poisson's ratio. The hexagonal periodic distribution of the pores makes the effective behavior isotropic. Both experimental tests and numerical simulations have been performed to determine the effective properties of the porous solid. A parametric study on the effect of the geometrical microstructural parameters is also presented. This auxetic structure is easy to fabricate and can be very useful in several engineering applications.
We would like to invite you to participate in the Symposium on Acoustic Metamaterials and Phononic Crystals at the ASME 2015 Applied Mechanics and Materials Conference (McMAT2015) to be held this summer from June 29 to July 1, 2015 in Seattle, Washington.
We would like to invite you to participate in the Annual Symposium on “Phononic Crystals and Metamaterials” at the ASME International Mechanical Engineering Congress and Expo (IMECE) to be held in Montreal, Quebec (Nov. 14-20, 2014).
We are seeking a motivated PhD student (only a student currently in the US for an immediate start) to work as a Graduate Research Assistant in our NSF project titled "Metamaterial-Enhanced Electroelastoacoustic Energy Harvesting for Sensor Systems." This computational and experimental project will investigate electroelastoacoustically coupled linear and nonlinear metamaterial-inspired piezoelectric energy harvesting concepts for self-powered sensor systems.
