On the Modelling of Salt Crystallization-Induced Damage in Layered Porous Materials

Abstract

In this contribution, the modelling of salt crystallization-induced damage in layered porous materials (such as masonry strengthened with composites, glazed earthenware, etc.) is addressed through a staggered multiphysics method. A staggered interchange of data is pursued between a multiphase model (crystallization pressure) and a macro-scale nonlinear mechanical model (material damage). Such method is preliminary applied to layered porous materials through a simple benchmark. Accordingly, the effects of layers with different properties on the crystallized salt distribution and damage pattern are highlighted.
