Thermal Degradation of Marble: Indications From Finite-Element Modelling

Abstract

Microstructure-based finite element simulations were used to study theThermo-mechanical behavior of calcite marbles. Give the same microstructure, a strongly textured marble had smaller elastic strain energy and a distinct directional dependence of thermal degradation compared to a weakly textured marble. This result of modelling coincides with observations from thermalexpansion experiments. Different boundary conditions assumed in the model calculations have been proven to be important for magnitude and pattern of thermally-induced microcracks. Microstructure-based finite element simulations are considered an excellent tool for elucidating influences of the rock's fabric on the thermal degradation of marbles.
