Elastocapillary morphing of self-encapsulated droplets floating at the oil-air interface
D. Andrini, D. Riccobelli, L. Gazzera +3
Self-encapsulated droplets floating at an oil--air interface undergo striking shape changes during evaporation, including flattening and localized loss of membrane tension leading…
Tunable morphing of electroactive dielectric-elastomer balloons
Yipin Su, Davide Riccobelli, Yingjie Chen +2
Designing smart devices with tunable shapes has important applications in industrial manufacture. In this paper, we investigate the nonlinear deformation and the morphological tran…
Flattened and wrinkled encapsulated droplets: Shape-morphing induced by gravity and evaporation
Davide Riccobelli, Hedar H. Al-Terke, Päivi Laaksonen +5
We report surprising morphological changes of suspension droplets (containing class II hydrophobin protein HFBI from Trichoderma reesei and water) as they evaporate with a contact…
The Föppl-von Kármán equations of elastic plates with initial stress
P. Ciarletta, G. Pozzi, D. Riccobelli
Initially stressed plates are widely used in modern fabrication techniques, such as additive manufacturing and UV lithography, for their tunable morphology by application of extern…
Morphomechanical model of the torsional c-looping in the embryonic heart
Giulia Bevilacqua, Pasquale Ciarletta, Alfio Quarteroni
Before septation processes shape its four chambers, the embryonic heart is a straight tube that spontaneously bends and twists breaking the left-right symmetry. In particular, the…
Torsion instability of soft solid cylinders
Pasquale Ciarletta, Michel Destrade
The application of pure torsion to a long and thin cylindrical rod is known to provoke a twisting instability, evolving from an initial kink to a knot. In the torsional parallel-pl…
Morphology of residually-stressed tubular tissues: Beyond the elastic multiplicative decomposition
Pasquale Ciarletta, Michel Destrade, Artur L. Gower +1
Many interesting shapes appearing in the biological world are formed by the onset of mechanical instability. In this work we consider how the build-up of residual stress can cause…
Learning patient-specific parameters for a diffuse interface glioblastoma model from neuroimaging data
Abramo Agosti, Pasquale Ciarletta, Harald Garcke +1
Parameters in mathematical models for glioblastoma multiforme (GBM) tumour growth are highly patient specific. Here we aim to estimate parameters in a Cahn-Hilliard type diffuse in…
The self-organised, non-equilibrium dynamics of spontaneous cancerous buds
Abramo Agosti, Stefano Marchesi, Giorgio Scita +1
Tissue self-organization into defined and well-controlled three-dimensional structures is essential during development for the generation of organs. A similar, but highly deranged…
On the existence of elastic minimizers for initially stressed materials
Davide Riccobelli, Abramo Agosti, Pasquale Ciarletta
A soft solid is said to be initially stressed if it is subjected to a state of internal stress in its unloaded reference configuration. Developing a sound mathematical framework to…
Morpho-elastic model of the tortuous tumour vessels
Davide Riccobelli, Pasquale Ciarletta
Solid tumours have the ability to assemble their own vascular network for optimizing their access to the vital nutrients. These new capillaries are morphologically different from n…
Shape transitions in a soft incompressible sphere with residual stresses
Davide Riccobelli, Pasquale Ciarletta
Residual stresses may appear in elastic bodies due to the formation of misfits in the micro-structure, driven by plastic deformations, thermal or growth processes. They are especia…
Rayleigh-Taylor instability in soft elastic layers
Davide Riccobelli, Pasquale Ciarletta
This work investigates the morphological stability of a soft body composed of two heavy elastic layers, attached to a rigid surface and subjected only to the bulk gravity force. Us…
A new restriction for initially stressed elastic solids
Artur Lewis Gower, Tom Shearer, Pasquale Ciarletta
We introduce a fundamental restriction on the strain energy function and stress tensor for initially stressed elastic solids. The restriction applies to strain energy functions …
Shear instability in skin tissue
Pasquale Ciarletta, Michel Destrade, Artur L. Gower
We propose two toy-models to describe, predict, and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of gr…
