Axisymmetric JKR-type adhesive contact under equibiaxial stretching

Submitted by Antonio Papangelo on
 Our research has just been published in Journal of Adhesion. It deals with axisymmetric frictionless adhesive contact problem for a spherical indenter pressed against an isotropic elastic incompressible half-space under equibiaxial stretching is studied in the framework of the generalized Johnson{Kendall{Roberts (JKR) theory, which accounts for the effect of weak coupling between fracture modes I and II by means of a phenomenological mode-mixity function. The model predicts that contact area can withstand a larger level of the substrate stretch under moderate pre-pulling force.

Hi all, 

Just wanted to share that the first issue of Matter was released last week. Matter is a new materials science journal from Cell Press. Our goal is to be a high impact offering, on par with Nature Materials. Check out our first issue here:

A comment on "A dimensionless measure for adhesion and effects of the range of adhesion in contacts of nominally flat surfaces" by M. H. Muser

Submitted by Mike Ciavarella on

I attach a Letter I sent to the Editor of a tribology journal, concerning adhesion of rough surfaces. 

I contend that some "criteria" that have been proposed based on extrapolation of numerical results are due to the limitations in present numerical sophisticated rough contact simulations, which only span at most 3 orders of magnitude of wavelengths, so typically people simulate from nanometer to micrometer scale.

Size-dependent mechanical behaviour of nanowires: an overview

Submitted by MNasr on

A recent study reviews achievements made in the determination of the size‐dependent mechanical properties of nanowires. Covering both measurement techniques and computational approaches, data reported in the literature are summarized for a variety of nanowires.
