Postdoc position in mechanics of metamaterials at the University of Minnesota

Submitted by stefanogonella on

A postdoc position in the area of mechanics of metamaterials is available in the group of Prof. Stefano Gonella (http://personal.cege.umn.edu/~gonella/) at the University of Minnesota. This exciting opportunity is in the context of a National Science Foundation (NSF)-funded interdisciplinary project whose main objective is to investigate the behavior of innovative topological metamaterials with asymmetric wave transport capabilities.

Nature paper about mechanical metamaterials violating Betti's theorem

Submitted by Mike Ciavarella on

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.

PhD position in Mechanics and Dynamics at Wichita State University

Submitted by Bhisham Sharma on

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.

PhD positions in the broad area of mechanics of advanced materials are available in the group of Prof. Stefano Gonella (http://personal.cege.umn.edu/~gonella/) at the University of Minnesota.

PhD Positions Available in Solid Mechanics and Advanced Materials

Submitted by Lifeng Wang on

Two PhD positions are available immediately in the Department of Mechanical Engineering at State University of New York (SUNY) Stony Brook University, New York, US.

The research program is about mechanics and multifunctional applications of new advanced materials (such as polymer cellular solids, polymer composites, and metamaterials) focusing on mechanical performance, 3D printing, acoustic/elastic wave propagation, energy absorption, and impact resistance. The candidates with background in solid mechanics and finite element analysis are highly encouraged to apply. 

[Call for Abstract] SES 2016 Symposium F-3: Wave Phenomena in Linear and Nonlinear Metamaterials

Submitted by stefanogonella on

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.

Symposium Technical Description

Continuous and discrete microstructured materials with null Poisson's ratio

Submitted by Giorgio Carta on

In this paper we propose diff erent 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 eff ective Poisson's ratio equal to zero. The connection between microstructural parameters and eff ective properties is shown in detail both analytically and numerically.

Design of a porous material with isotropic negative Poisson's ratio

Submitted by Giorgio Carta on

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 e ffective behavior isotropic. Both experimental tests and numerical simulations have been performed to determine the e ffective properties of the porous solid. A parametric study on the e ffect of the geometrical microstructural parameters is also presented. This auxetic structure is easy to fabricate and can be very useful in several engineering applications.
