6th International Workshop on Rock Physics: A Coruña, Spain 13 -17 June 2022: Book of Abstracts
Delgado Martín, Jordi; Muñoz-Ibáñez, Andrea; Falcón-Suárez, Ismael Himar (Universidade da Coruña, Servizo de Publicacións, 2022)[Abstract] The 6th International Workshop on Rock Physics (6IWRP) was held A Coruña, Spain, between 13th and 17th of June, 2022. This meeting follows the track of the five successful encounters held in Golden (USA, 2011), ... -
Anisotropic deformability and strength of slate from NW-Spain
Alejano, Leandro R.; González Fernández, Manuel Alejandro; Estévez-Ventosa, Xian; Song, Fei; Delgado Martín, Jordi; Muñoz-Ibáñez, Andrea; González-Molano, Nubia; Alvarellos-Iglesias, José (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 ... -
Experimental Investigation of Mode I Rock Fracture Toughness
Muñoz-Ibáñez, Andrea (2020)[Abstract] Mode I fracture toughness (KIC) is one of the most important parameters in rock fracture mechanics. KIC is an intrinsic material property that represents the ability of a material containing a pre-existing defect ... -
Hydrofracturing tests on granite samples using a true triaxial device equipped with acoustic emission sensors
Herbón-Penabad, Miguel; Muñoz-Ibáñez, Andrea; Delgado Martín, Jordi; González-Molano, Nubia; Alvarellos-Iglesias, José; Canal, Jacobo (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 ... -
Hydrostatic, strike-slip and normal stress true triaxial hydrofracturing testing of Blanco Mera Granite: breakdown pressure and tensile strength assessment
Muñoz-Ibáñez, Andrea; Herbón-Penabad, Miguel; Delgado Martín, Jordi; Alejano, Leandro R.; Alvarellos-Iglesias, José; Canal, Jacobo (Springer, 2023)[Abstract:] We have designed and built a versatile testing device to perform hydraulic fracturing experiments under true triaxial conditions. The device, based on a stiff biaxial frame that can be installed in a servocontrolled ... -
Photoelastic Stress Analysis of Mode I Fracture Toughness Tests Using PMMA Samples
Muñoz-Ibáñez, Andrea; Herbón-Penabad, Miguel; Delgado Martín, Jordi (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 ... -
Pure Mode I Fracture Toughness Determination in Rocks Using a Pseudo-Compact Tension (pCT) Test Approach
Muñoz-Ibáñez, Andrea; Delgado Martín, Jordi; Costas, Miguel; Rabuñal, Juan R.; Alvarellos-Iglesias, José; Canal, Jacobo (Springer Nature, 2020-07)[Absctract]: Mode I fracture toughness (KIC) quantifies the ability of a material to withstand crack initiation and propagation due to tensile loads. The International Society for Rock Mechanics (ISRM) has proposed four ... -
Size Effect and Other Effects on Mode I Fracture Toughness Using Two Testing Methods
Muñoz-Ibáñez, Andrea; Delgado Martín, Jordi; Juncosa, Ricardo (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 ...
