a JKR theory of adhesion for anisotropic solids

Jim Barber and I just got accepted this paper in JMPS, and it is also already available on Arxiv.  We found a remarkably simple closed form solution for adhesion on orthotropic materials in the planes of symmetry.  This shows adhesion can increase significantly due to anisotropy, namely the JKR solution continues to hold in the sense of mean elastic modulus, but the prefactor can grow without limit. We expect applications in crystals indentation, but also in locomotion in biological world.

Journal Club Theme of March 2013: Interfacial Adhesion of Graphene - Measurements and Analysis

Several recent papers have reported measurements of adhesion energy between graphene and other materials (e.g., Si/SiOx and copper) [1-3]. Like thin films, many experimental methods may be adopted to measure the interfacial properties of graphene, such as the pressurized blister test [2] and the double-cantilever beam test [3]. The challenges lie in the handling of atomically thin membranes and analysis/interpretation of the data.

Fatigue of polymer-supported Ag thin films

The fatigue behavior of Ag films on polyethyleneterephthalate substrates was studied using electrical resistance measurements.
Scanning electron microscopy images showed two types of failure: typical fatigue failure with extrusion–intrusion pairs, and ductile
failure with local necking. Once through-thickness cracks are formed in the metal layer, cracks propagate and the resistance increases abruptly for both failure modes. The effect of adhesion on fatigue life is discussed in terms of concurrent delamination, crack initiation and propagation.

Fracture in Composite/Aluminium Joints of Variable Adhesive Properties

Hello everyone,

 

One of the papers from the 'past' (but still quite actual...I think) and maybe of some interest to various communities. 

 

Abstract:

A system in which one adherend had two types of surface treatment was tested using a wedge test.

Simple polishing and polishing with subsequent sandblasting were the

treatments used, with a distinct straight line, perpendicular to the sample edges,

separating the two. Despite the clear-cut difference in surface treatment, smooth

Two Nano-Tribology postdoctoral positions in Tel Aviv University


Two postdoctoral positions are available in the group of Prof. M. Urbakh in lively Tel-Aviv. Topics are centered around nano and micro-scale tribology (friction, dissipation, adhesion, wear) involving theory, modeling, and computer simulation of frictional and nonlinear
dissipation phenomena.

ASME IMECE 2012, “Mechanics of Adhesion” symposium


Adhesion has long been an important issue for mechanics and
many other disciplines. Its influence spans macro-, micro-, nano- and molecular
scales. When size goes down, adhesion plays a more and more significant role.
Many important technologies attribute to adhesion, such as transfer printing
for advanced microfabrication, super adhesives inspired by gecko foot hairs,
and self-assembly. Adhesion also has strong implications on the behavior of
nanomaterials (such as nanotubes and graphenes) and biological systems (such as
cells). This minisymposium "Mechanics of Adhesion" is to provide a

Determining Graphene Adhesion via Substrate-regulated Morphology of Graphene

Understanding the adhesion between graphene and other materials is crucial for achieving more reliable graphene-based applications in electronic devices and nanocomposites. The ultra-thin profile of graphene, however, poses significant challenge to direct measurement of its adhesion property using conventional approaches. We show that there is a strong correlation between the morphology of graphene on a compliant substrate with patterned surface and the graphene-substrate adhesion.

Journal Club February 2010: Mechanics of Patterned and Structured Interfaces

Welcome to February 2010 Journal Club!  This month, I look forward to a lively discussion on the mechanics of structured and patterned interfaces in which geometry is used to tailor adhesion.  Much of the work in this area has been inspired by a variety of animals and insects that have feet covered with small structures (often hierarchical and sub-micrometer in size at the end) that allow them to strongly adhere to a broad range of surfaces.  The best known example is the Tokay Gecko (Gekko gecko), which can achieve an adhesion force much greater than its body weight and can quickl

Journal Club Theme of Jan. 1 2008: Role of Mechanics in Biomimetics

With the beginning of the year 2008, the iMechanica journal club moves to two topics per month.  This first topic will be highlighted here for 1-14 January, with the next topic starting on 15 January. 

State-of-the-art understanding of cracking for porous materials?

It seems there are quite a few experimental studies [1,2] on the fracture properties of porous materials, like nanoporous low-k dielectrics, as a function of porosity. Can anyone point out some references on the theoretical part, like the available models, computational methods or analytical approaches that can capture microstructure information, including porosity, pore geometry etc. Interface delamination of porous materials is also of interest. Thanks.
