Finite deformations induce friction hysteresis in normal wavy contacts
M. Ceglie, G. Violano, L. Afferrante +1
Since Hertz's pioneering work in 1882, contact mechanics traditionally grounds on linear elasticity, assuming small strains and displacements. However, recent experiments clearly h…
Role of viscoelasticity in the adhesion of mushroom-shaped pillars
Guido Violano, Savino Dibitonto, Luciano Afferrante
Mushroom-shaped pillars have been extensively studied for their superior adhesive properties, often drawing inspiration from natural attachment systems observed in insects. Typical…
Adhesive contact mechanics of bio-inspired pillars: exploring hysteresis and detachment modes
Guido Violano, Savino Dibitonto, Luciano Afferrante
Engineering technologies frequently draw inspiration from nature, as exemplified in bio-inspired adhesive surfaces. These surfaces present textures adorned by pillars, mimicking th…
On the long and short-range adhesive interactions in viscoelastic contacts
Guido Violano, Luciano Afferrante
Recently, tribologists have shown increasing interest in rate-dependent phenomena occurring in viscoelastic fractures. However, in some cases, conflicting results are obtained desp…
Size effects in adhesive contacts of viscoelastic media
Guido Violano, Luciano Afferrante
Is the maximum force required to detach a rigid sphere from a viscoelastic substrate dependent on the initial value of the contact radius? Experimental and theoretical investigatio…
On the effective surface energy in viscoelastic Hertzian contacts
Luciano Afferrante, Guido Violano
Viscoelasticity and rate-dependent adhesion of soft matter lead to difficulties in modeling the 'relatively simple' problem of a rigid sphere in contact with a viscoelastic half-sp…
