Enhancement of adhesion strength through microvibrations: modeling and experiments
Michele Tricarico, Michele Ciavarella, Antonio Papangelo
High-frequency micrometrical vibrations have been shown to greatly influence the adhesive performance of soft interfaces, however a detailed comparison between theoretical predicti…
Bulk and fracture process zone contribution to the rate-dependent adhesion amplification in viscoelastic broad-band materials
Ali Maghami, Qingao Wang, Michele Tricarico +3
The contact between a rigid Hertzian indenter and an adhesive broad-band viscoelastic substrate is considered. The material behaviour is described by a modified power law model, wh…
Viscoelastic amplification of the pull-off stress in the detachment of a rigid flat punch from an adhesive soft viscoelastic layer
Ali Maghami, Michele Ciavarella, Antonio Papangelo
The problem of the detachment of a sufficiently large flat indenter from a plane adhesive viscoelastic strip of thickness "b" is studied. For any given retraction speed, three diff…
A two-scale FEM-BAM approach for fingerpad friction under electroadhesion
Fabian Forsbach, Markus Heß, Antonio Papangelo
The complex physics behind electroadhesion-based tactile displays poses an enormous modeling challenge since not only the fingerpad structure with multiple nonlinear layers, but al…
Detachment of a rigid flat punch from a viscoelastic material
Antonio Papangelo, Michele Ciavarella
We show that the detachment of a flat punch from a viscoelastic substrate has a relatively simple behavior, framed between the Kendall's elastic solution at the relaxed modulus and…
Shear-induced contact area anisotropy explained by a fracture mechanics model
A. Papangelo, J. Scheibert, R. Sahli +2
This paper gives a theoretical analysis for the fundamental problem of anisotropy induced by shear forces onan adhesive contact, discussing the experimental data of the companion L…
On stickiness of multiscale randomly rough surfaces
G. Violano, L. Afferrante, A. Papangelo +1
We derive a very simple and effective stickiness criterion for solids having random roughness using a new asymptotic theory, which we validate with that of Persson and Scaraggi and…
Multistability and localization in forced cyclic symmetric structures modelled by weakly-coupled Duffing oscillators
A. Papangelo, F. Fontanela, A. Grolet +2
Many engineering structures are composed of weakly coupled sectors assembled in a cyclic and ideally symmetric configuration, which can be simplified as forced Duffing oscillators.…
The role of adhesion in contact mechanics
M. Ciavarella, J. Joe, A. Papangelo +1
Adhesive [e.g. van der Waals] forces were not generally taken into account in contact mechanics until 1971, when Johnson, Kendall and Roberts (JKR) generalized Hertz' solution for…
On mixed-mode fracture mechanics models for contact area reduction under shear load in soft materials
A. Papangelo, M. Ciavarella
The fundamental problem of friction in the presence of macroscopic adhesion, as in soft bodies, is receiving interest from many experimentalists. Since the first fracture mechanics…
Adhesion of surfaces with wavy roughness and a shallow depression
Michele Ciavarella, Antonio Papangelo
Recently, a simple and elegant "dimple" model was introduced by McMeeking et al. (Adv Eng Mat 12(5), 389-397, 2010) to show a mechanism for a bistable adhesive system involving a s…
Fracture Mechanics implications for apparent static friction coefficient in contact problems involving slip-weakening laws
A. Papangelo, M. Ciavarella, J. R. Barber
We consider the effect of differing coefficients of static and dynamic friction coefficients on the behaviour of contacts involving microslip. The classic solutions of Cattaneo and…
