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 ... -
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 ... -
Size effects on the tensile strength and fracture toughness of granitic rock in different tests
Pérez-Rey, Ignacio; Muñoz-Ibáñez, Andrea; González-Fernández, Manuel A.; Muñiz-Menéndez, Mauro; Herbón-Penabad, Miguel; Estévez-Ventosa, Xian; Delgado Martín, Jordi; Alejano, Leandro R. (Elsevier, 2023)[Abstract:] This study investigates the tensile failure mechanisms in granitic rock samples at different scales by means of different types of tests. To do that, we have selected a granitic rock type and obtained samples ...
