The second deadline to apply for a PhD position in Mathematical Analysis, Modelling and Applications at SISSA (Scuola Internazionale Superiore di Studi Avanzati - www.sissa.it) is August 20, 2020 at noon (Rome time). There are 5 PhD grants available.

Dear iMechanica researchers,

I'd like to share an opinion paper that was written by Rui Huang, Kenneth Liechti, Nanshu Lu, and I for Current Opinion in Solid State & Materials Science. The aim is to discuss the mechanics research on 2D material interfaces in terms of recent developments and appeared challenges and opportunities. Here is the link; Below, I also attached a copy of the manuscript and pasted the Abstract.

I have a postdoc position for a project involving the design of bioinspired composites for real applications.

In the case of orthotropic materials like wood or composites, transverse shear has an effect on the modulus determination by bending tests. A procedure based on three-point bending is proposed. The experimental data required are the load and displacement given by the testing machine. The novelties of the proposal are:

The Department of Engineering at Aarhus University has a number of open positions as Assistant Professor (tenure track) or Associate Professor at the Section of Mechanical Engineering. The University seeks innovative and visionary engineers/researchers capable of developing the research and teaching in Mechanical Engineering.

The positions are available from February 1, 2021 or as soon as possible hereafter.

The electroadhesive contact between a conductive sphere with a rigid substrate, both coated with an electrically insulating layer is studied, by adopting two solution strategies: (i) a DMT approximation and (ii) an iterative finite element model which accounts for the effect of the electroadhesive tractions on the deformation of the elastic solids. The contact problem is solved by varying the applied voltage and the elastic modulus of the coating layer.

Transverse wrinkles commonly occur in a uniaxially tensile elastic membrane and can vanish upon excess stretching. The wrinkling direction is usually perpendicular to the stretching direction under isotropic elasticity. Here, we show that wrinkles are orientable by material anisotropy, such as in fiber-reinforced or fibrous films, and the wrinkling orientation can be tuned by varying the stiffness and direction of fibers.

PhD position is available in Flash X-ray radiography for impact/penetration experiments

How many people were involved in the covid-19 epidemic during the Italian Lockdown in Lombardy, Valle d'Aosta, Veneto and Emilia Romagna? 

How open data on infected and recovered individuals were biased by the limited extent in the use of medical swabs? 

How lockdown measures have influenced the spread of covid-19 epidemic in the above regions? 

A Postdoctoral Research Associate Position is available (Fall 2020) in Professor R. Thevamaran’s laboratory at the Department of Engineering Physics of the University of Wisconsin-Madison to study the dynamic behavior of hierarchical materials.
