 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.

We are pleased to invite applications for a PhD position in the new four-year EU-funded Marie Sklodowska-Curie ITN programme “INSPIRE - INNOVATIVE GROUND INTERFACE CONCEPTS FOR STRUCTURE PROTECTION”. This network is led by National Technical University of Athens and consists of 7 European universities (Univ. of Trento, ETH, Univ. of Lille, Technical University of Kaiserslautern, Univ. of Mons, Univ of Bologna) 1 Research Institute (Centre National de la Recherche Scientifique) as well as 5 industrial partners (RINAC,FIP, ADT, IGF, GRSc).

On incompressibility constraint and crack direction in soft solids

Submitted by Konstantin Volokh on

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

Submitted by Ahmed Elbanna on

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.
