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…
Bayesian methods for the identification of model parameters for water transport in porous media
Paola Stolfi, Elia Onofri, Gabriella Bretti
The structure of the nonlinear inverse problem arising from capillarity-driven imbibition in porous media is investigated, considering a degenerate parabolic PDE with compactly sup…
Dissolution of carbonate stones caused by CO2 pollutant: an erosion model
Elishan Christian Braun, Gabriella Bretti, Samuele Ferri +2
In this paper we introduce a new mathematical model describing the erosion process caused in carbonate stones by the dissolution of the porous matrix due to the penetration of carb…
Structural Identifiability and Comparative Calibration of Water Retention Curves for Imbibition in Porous Media
Gabriella Bretti, Maurizio Ceseri, Elia Onofri +1
This paper investigates the structural identifiability and a comparative calibration of four water retention curves (WRCs) within the framework of the Richards equation coupled wit…
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…
Data-Informed Mathematical Characterization of Absorption Properties in Artificial and Natural Porous Materials
Elishan C. Braun, Gabriella Bretti, Melania Di Fazio +2
In this work, we characterize the water absorption properties of selected porous materials through a combined approach that integrates laboratory experiments and mathematical model…
