Theory of fracture initiation and propagation in viscoelastic media
Giuseppe Carbonea, Cosimo Mandriotab, Guido Violanob +2
Crack initiation and propagation are fundamental problems in materials science, often leading to catastrophic failure. While fracture in elastic solids occurs instantaneously above…
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…
