Experimental Study of Fracture Toughness in Sedimentary Rocks
Brevik, Niklas Øystad (Master thesis, 2016)This master thesis details the determination of mode I (tensile) fracture toughness, KIC, using the International Society of Rock Mechanics (ISRM) Chevron Bend (CB) method on three sedimentary rock types. Fracture toughness ... -
Laboratory Measurements of Strength Parameters for Fracturing
Walle, Lars Erik; Stroisz, Anna Magdalena; Brevik, Niklas Øystad; Jensen, Stina Stokmo; Holt, Rune Martin (Chapter, 2017)Fracture toughness and tensile strength are rock parameters that have influence on hydraulic fracture initiation and propagation, and that to various degrees are implemented in fracture modeling tools. Laboratory measurements ...
