A USACM Thematic Workshop on Recent Advances in Computational Methods for Nanoscale Phenomena will be held at the University of Michigan in Ann Arbor from August 29-31, 2016. The workshop website contains further information at http://acm-nano2016.usacm.org.
Two-Dimensional (2D) materials have been widely studied since the discovery of graphene in 2004. Many of the initial works on the various 2D materials (graphene, MoS2 and other transition metal dichalcogenides, black phosphorus, and others like the monochalcogenides) by mechanicians focused on issues like ideal strength, and appropriate methods to calculate the bending modulus. Some of these, and other issues, were reviewed by Sulin Zhang in a J-Club from March 2015 (http://imechanica.org/node/17999). That was a nic
We are offering a PhD position to start this coming september at technion, Haifa, Israel, as advertised in the attached file.
To qualify, the candidates should hold an M.Sc. with thesis in mechanical/materials engineering and have passed the GRE with a grade of 85% or more.
The research will be experimental and numerical in character.
The Cardiac Biomechanics Laboratory at the University of California San Francisco Medical Center (UCSF) Division of Cardiothoracic Surgery and San Francisco VA Medical Center is seeking a hard working, motivated post-doctoral fellow to participate in biomedical engineering research involving the ascending thoracic aortic aneurysms (aTAA). The post-doctoral fellow should be motivated to be on a career track to become an academic professor. Our lab is NIH funded to investigate the biomechanics of aortic aneurysms and currently has 2 postdoctoral fellows, and are seeking a 3rd.&nbs
In this paper we formulate a nonlinear elasticity theory in which the ambient space is evolving. For a continuum moving in an evolving ambient space, we model time dependency of the metric by a time-dependent embedding of the ambient space in a larger manifold with a fixed background metric. We derive both the tangential and the normal governing equations. We then reduce the standard energy balance written in the larger ambient space to that in the evolving ambient space.
Dear Professors,
I am Xilei BIAN, from Shanghai University. I will complete my Ph. D degree this year, and I wish to apply a postdoctoral position related to nanostructured materials or advanced materials.
I am familiar with and skilled in: Synchrotron Source and the data process, in-situ TEM/SEM, FIB, Instrumented nanoindentation, mechanical testing machine, XRD, DSC, etc.
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:
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 di fferential 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.
This work introduces a new microscopically-motivated model for the electromechanical response of elastomers:
The merit of this novel model is demonstrated in the following paper
