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.
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.

1. Introduction
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:

Hello all,
I am looking for the following paper: Nash, C. D. "Fatigue of self-healing structure-a generalized theory of fatigue failure." MECHANICAL ENGINEERING. Vol. 89. No. 2. 345 E 47TH ST, NEW YORK, NY 10017: ASME-AMER SOC MECHANICAL ENG, 1967.
Unfortunately, I couldn't find it anywhere. Even I ordered it through RACER but they sent the abstract to me. I would really appreciate it if someone can provide me with this paper.
regards,
Faezeh
Most of the research carried out on hypervelocity collisions, of the kind encountered in space, assume that the projectile hits a stationary target. In reality, both the target and the projectile are moving at high velocity in a non-colinear fasion. We present here a study of this phenomenon and its rfelationship with oblique impact.
A number of authors have experimentally assessed the influence of friction on adhesive contacts, and generally the contact area has been found to decrease due to tangential shear stresses at the interface. The decrease is however generally much smaller than that predicted already by the Savkoor and Briggs 1977 classical theory using “brittle” fracture mechanics mixed mode model extending the JKR (Griffith like) solution to the contact problem.
