The Nanoscale Mechanics and Materials Laboratory (NMML) at the University of California, Irvine is currently accepting applications for two postdoctoral scholar positions.  One opening has a focus on experimental research, while the other is seeking a computational scientist.

Experimental Postdoc in Small-Scale Mechanical Testing

Dear colleague,

We encourage you to submit an abstract to the symposium "Multi-scale Mechanics of Particulate Media" (Symposium D-1) within the "Mechanics of Solids and Structures" track of the 53rd Annual Technical Meeting of the Society of Engineering Science (SES) to be held at the University of Maryland, October 2-5, 2016. The symposium description may be found below. For further details and to submit an abstract, please see the meeting website: ses2016.org. The abstract submission deadline is June 15, 2016.

The paper presents a novel analysis of localisation and transmission properties of randomly-perturbed flexural systems. Attention is given to the study of propagation regimes and the connection with localised resonance modes in the context of Anderson's localisation. The analytical study is complemented with numerical simulations relevant to the design of efficient vibration isolation systems.

Eigenvalues, reflected and transmitted energy, localisation factors for the examined bi-coupled random system:

ASWC will be attended by over 350 professionals from over a 100 companies and organizations. AT the event 70 presentations will be delivered by experts from major global car, truck and off-highway manufacturers, tier-1 suppliers, prominent universities, and research centers. Attendees will have a unique opportunity to meet automotive simulation leaders, see how major global companies are using simulation, learn best practices, see the latest technology advances, and network with peers from around the world.

Department of Engineering (ENG), Aarhus University (AU) invites applications for a number of positions as tenure track assistant professors or associate professors in the field of Mechanical Engineering (ME). The University has ambitious plans to increase its activities significantly within research and education as well as public and industrial collaboration with the vision of bringing AU into the global engineering elite.

Large-eddy simulation (LES) and Reynolds-averaged Navier-Stokes (RANS) simulation of wind and wave forced oceanic turbulence in unstratified shallow water are performed in order to investigate the influence of wall modeling on results. The LES is also used to investigate the dependence of results on downwind and crosswind lengths of the computational domain, representative of a shallow shelf coastal ocean (10-to-30 m deep) unaffected by lateral boundaries.

We are concerned with underlying connections between fluids,
elasticity, isometric embedding of Riemannian manifolds, and the existence of
wrinkled solutions of the associated nonlinear partial differential equations. In
this paper, we develop such connections for the case of two spatial dimensions,
and demonstrate that the continuum mechanical equations can be mapped into
a corresponding geometric framework and the inherent direct application of
the theory of isometric embeddings and the Gauss-Codazzi equations through
examples for the Euler equations for fluids and the Euler-Lagrange equations
for elastic solids. These results show that the geometric theory provides an
avenue for addressing the admissibility criteria for nonlinear conservation laws
in continuum mechanics.
