Numerical Modeling of Crystallization-Induced Fracturing in Porous Limestone
This paper presents a computational model coupling heat, water and salt ion transport, salt crystallization, mechanical stresses and fracturing in porous materials, including the damage evolution with time. A continuous-discontinuous framework was developed, accounting for the interaction between discrete fractures and the surrounding porous material. The capabilities of the model are illustrated by a simulation example describing a wet pedestal, saturated with sodium sulfate solution, in which in-pore crystallization is induced by cooling. The combination of crystallization and thermal stresses gives rise to the development of two distinct types of crack formation in a single structure. These results show the potential of the model to predict physical material degradation under complex conditions.
