Size Effect and Other Effects on Mode I Fracture Toughness Using Two Testing Methods
(Elsevier, 2021)
[Abstract] Mode I fracture toughness (KIC) is an intrinsic material property that quantifies its resistance to tensile fracture propagation. The International Society for Rock Mechanics has endorsed four methods to determine ...
Photoelastic Stress Analysis of Mode I Fracture Toughness Tests Using PMMA Samples
(IOP Publishing Ltd, 2021)
[Abstract] Rocks are usually inhomogeneous and anisotropic materials. The presence of foliation planes, grain boundaries or even microcracks may alter the stress distribution. In order to identify whether unusual behaviours ...
Hydrofracturing tests on granite samples using a true triaxial device equipped with acoustic emission sensors
(IOP Publishing Ltd, 2021)
[Abstract:] We present a series of tests performed on granite samples using a true triaxial device designed and built at the Rock Mechanics Laboratory (University of A Coruña). The experiments were performed using cubic ...
Anisotropic deformability and strength of slate from NW-Spain
(Elsevier, 2021)
[Abstract:] Slates are metamorphic rocks characterized by the pervasive occurrence of cleavage or foliation producing a highly anisotropic mechanical behavior characterized by fissility. Deformability and strength of these ...
