Axisymmetric JKR-type adhesive contact under equibiaxial stretching

 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.

On incompressibility constraint and crack direction in soft solids

Most soft materials resist volumetric changes much more than shape distortions. This experimental observation led to the introduction of the incompressibility constraint in the constitutive description of soft materials. The incompressibility constraint provides analytical solutions for problems which, otherwise, could be solved numerically only. However, in the present work, we show that the enforcement of the incompressibility constraint in the analysis of failure of soft materials can lead to somewhat non- physical results.

Characterization of fracture in topology-optimized bio-inspired networks

In this paper we present a methodology for reverse engineering of trabecular bone like architectures using multi-objective topology optimization. We then investigate the mechanical properties of the resulting network structures. Specifically, we show that structures optimized according to Wolff's law alone may be stiffest but they are also fragile.

On the application of fracture mechanics mixed-mode models of sliding with friction and adhesion --- the Menga, Carbone & Dini paradox

I attach a PREPRINT of a paper on the Menga, Carbone & Dini paradox (published in JMPS last year, available at, that is on the application of thermodynamics to mixed mode fracture mechanics models of contacts with friction and adhesion, and an apparent paradox which emerges from this treatment.  Comments welcome.

JSPS Postdoctoral Fellowships in Japan - 2 years - Deadline 10th August

Dear Friends,

I am looking for a postdoctoral candidate who wishes to apply for a JSPS (Japan Society for the Promotion of Science) fellowship.

This fellowship is a highly competitive scheme and includes a generous monthly salary (at the current exchange rate, around 3000 Euro or 3300 $) plus airfare (round-trip ticket to Japan).

I will support the application as a host and will help writing the proposal.
Applicants are allowed to suggest their own project, but preference will be given to candidates with experience and interest in two topics:

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

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.

Mechanical characterisation of lignocellulosic fibres using toy bricks tensile tester

This paper demonstrates the potential use of toy-bricks as the building block of a mechanical tensile testing instrument for the mechanical characterisation of natural fibres. A table-top tensile testing instrument was developed using LEGO parts (Mindstorms EV3 and Technics) and a 2 kg capacity load cell, whereas deformation modes were programmed in an open source programming language. Experimental work was conducted on oil palm fibres under different tensile modes (i.e.

PhD position at the University of Sheffield: Tomography of Large Structural Elements

Large structural elements forming structures such as bridges, retaining walls and tunnel linings may contain hidden defects that limit their longevity, with major safety and cost implications. Also, when a structure is subjected to intense loading, internal damage may occur which is not visible on the surface.
