Mechanics at the interfaces of 2D materials

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 opportunitiesHere is the link; Below, I also attached a copy of the manuscript and pasted the Abstract.

3-point bending test procedure for obtaining flexural and shear modulus

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:

Electroadhesive sphere-flat contact problem

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.

A finite strain model predicts oblique wrinkles in stretched anisotropic films

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.

Machine learning and SIR epidemiological models applied to the analysis of the Italian Lockdown

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?

Phononic canonical quasicrystalline waveguides

I am glad to present a recent set of papers highlighting the noteworthy properties of 1D periodic waveguides generated by a quasicrystalline sequence. The concept of canonical configuration explains how to obtain a periodic frequency spectrum and why this outcome is connected to trace mapping:

how did fraeijs de veubeke pass away?

I see references to his "untimely death".  Yet, I have never been able to find out what happened.  I'm curious, does anyone know what happened to him?

Incidentally, many of his papers can be found at the following link for free:

https://orbi.uliege.be/browse?type=authorulg&rpp=20&value=Fraeijs+de+Veu...

I expect some of his papers would be of interest to mechanicians.
