A complete simulation framework for stone degradation on 3D real geometries
Silvia Preda, Gabriella Bretti, Francesco Freddi +2
We present a complete workflow for predicting stone degradation phenomena, such as marble sulfation, in works of art. The main challenge is to accurately acquire the geometry of th…
Finite elements for the space approximation of a differential model for salts crystallization
Alessandra Aimi, Gabriella Bretti, Giulia Di Credico +3
This article investigates a space-time differential model related to the degradation of stone artifacts caused by exposure to air and atmospheric agents, which specifically lead to…
Potential-based versus non potential-based cohesive models accounting for loading and unloading with application to sliding elastic laminates
Francesco Freddi, Filippo Riva
A rigorous unified perspective of cohesive zone models is presented, including and comparing potential-based and non potential-based formulations, and encompassing known examples s…
Predicting the impact of water transport on carbonation-induced corrosion in variably saturated reinforced concrete
E. Korec, L. Mingazzi, F. Freddi +1
A modelling framework for predicting carbonation-induced corrosion in reinforced concrete is presented. The framework constituents include a new model for water transport in cracke…
On a phase--field model of damage for hybrid laminates with cohesive interface
Elena Bonetti, Cecilia Cavaterra, Francesco Freddi +1
In this paper we investigate a rate--independent model for hybrid laminates described by a damage phase--field approach on two layers coupled with a cohesive law governing the beha…
A nonlinear model for marble sulphation including surface rugosity: theoretical and numerical results
Elena Bonetti, Cecilia Cavaterra, Francesco Freddi +2
We consider an evolution system describing the phenomenon of marble sulphation of a monument, accounting of the surface rugosity. We first prove a local in time well posedness resu…
