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 ... -
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 ... -
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 ...
