The Brittle-Ductile Transition in Porous Limestone : Failure Mode, Constitutive Modeling of Inelastic Deformation and Strain Localization
Understanding of the mechanics of the brittle-ductile transition (BDT) in porous limestone is significantly more challenging than for sandstone because of the lack of consistent acoustic emission activity in limestone, meaning that one must rely on alternative techniques. In this paper, we investigate systematically the failure modes in Indiana limestone using X-ray microComputed Tomography imagin
