Strain incompatibility as a source of residual stress in welding and additive manufacturing
Domenico Zaza, Michele Ciavarella, Giuseppe Zurlo
The accumulation of residual stress during welding and additive manufacturing is an important effect that can significantly anticipate the workpiece failure. In this work we exploi…
Comments on old and recent experiments of "stickiness" of a soft solid to a rough hard surface
Michele Ciavarella
The old asperity model of Fuller and Tabor had demonstrated almost 50 years ago surprisingly good correlation with respect to quite a few experiments on the pull-off decay due to r…
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
Michele Ciavarella
letter to the Editor of Trib.Int.
A simplified version of Persson's multiscale theory for rubber friction due to viscoelastic losses
Michele Ciavarella
We show the full multiscale Persson's theory for rubber friction due to viscoelastic losses can be approximated extremely closely to simpler models, like that suggested by Persson…
On the use of DMT approximations in adhesive contacts, with remarks on random rough contacts
Michele Ciavarella
The contact between rough surfaces with adhesion is an extremely difficult problem, and the approximation of the DMT theory (to neglect deformations due to attractive forces), orig…
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…
On the effect of wear on asperity heigth distributions, and the corresponding effect in the mechanical response
M. Ciavarella
Since the time of the original Greenwood & Williamson paper, it was noticed that abrasion and wear lead to possibly bimodal distribution of asperity height distribution, with the u…
On the significance of asperity models predictions of rough contact with respect to recent alternative theories
M. Ciavarella
Recently, it has been shown that while asperity models show correctly qualitative features of rough contact problems (linearity in area-load, negative exponential dependence of loa…
A note on the possibility of roughness enhancement of adhesion in Persson's theory
M. Ciavarella
In an attempt to model the observed enhancement of adhesion in some classical experiments in the 1970-1980's, Persson introduced in his theory of adhesion between rough solids a te…
A random process asperity model for adhesion
M. Ciavarella
A simple asperity model using random process theory is developed in the presence of adhesion. Using the DMT model for each individual asperity, and asymptotic results at large sepa…
Adhesive rough contacts near complete contact
M. Ciavarella
Recently, there has been some debate over the effect of adhesion on the contact of rough surfaces. Classical asperity theories predict, in agreement with experimental observations,…
JKR solution for an anisotropic half space
J. R. Barber, M. Ciavarella
In this paper, the classical JKR theory of the adhesive contact of isotropic elastic spheres is extended to consider the effect of anisotropic elasticity. The contact area will the…
