Spontaneous morphing of equibiaxially pre-stretched elastic bilayers: the role of sample geometry
Noè Caruso, Aleksandar Cvetković, Alessandro Lucantonio +2
An elastic bilayer, consisting of an equibiaxially pre-stretched sheet bonded to a stress-free one, spontaneously morphs into curved shapes in the absence of external loads or cons…
Coupled swelling and nematic reordering in liquid crystal gels
Alessandro Lucantonio, Antonio DeSimone
We derive a multiphysics model that accounts for network elasticity with spontaneous strains, swelling and nematic interactions in liquid crystal gels (LCGs). We discuss the coupli…
Concurrent factors determine toughening in the hydraulic fracture of poroelastic composites
Alessandro Lucantonio, Giovanni Noselli
Brittle materials fail catastrophically. In consequence of their limited flaw-tolerance, failure occurs by localized fracture and is typically a dynamic process. Recently, experime…
Large-strain poroelastic plate theory for polymer gels with applications to swelling-induced morphing of composite plates
Alessandro Lucantonio, Giuseppe Tomassetti, Antonio DeSimone
We derive a large-strain plate model that allows to describe transient, coupled processes involving elasticity and solvent migration, by performing a dimensional reduction of a thr…
Poroelastic toughening in polymer gels: A theoretical and numerical study
Giovanni Noselli, Alessandro Lucantonio, Robert M. McMeeking +1
We explore the Mode I fracture toughness of a polymer gel containing a semi-infinite, growing crack. First, an expression is derived for the energy release rate within the lineariz…
