Microstructural evolution of Carrara marble during semi-brittle deformation
Tongzhang Qu, Nicolas Brantut, David Wallis +1
Fifteen marble samples were subjected to semi-brittle deformation through triaxial compression experiments, reaching axial strains of 0.5%, 1.0%, 2.0%, 4.0%, or 7.5% at temperature…
