Introduction of the Lecture
Geomaterials exhibit heterogenous properties at all scales and the THM characterization processes can be influenced by the heterogeneities that can influence the specification of properties at the modelling scale and at the experimental bench-scale. Heterogeneity can also be introduced by processes such as micro-mechanical damage and defect development. The lecture will discuss the estimation of key parameters such as the elasticities, the Biot coefficient, the permeability and thermal conductivity of heterogeneous limestones and granitic rocks.
