Fracture toughness determination and micromechanics of rock under mode I and mode II loading
Summary
This thesis describes a new experimental method for measuring shear (Mode II) fracture toughness in rock, comparing it to tensile fracture testing. This rock mechanics study has no connection to microplastics or environmental health.
This thesis work describes a new experimental method for the determination of Mode II (shear) fracture toughness, KIIC, of rock and compares the outcome to results from Mode I (tensile) fracture toughness, KIC, testing using the International Society of Rock Mechanics (ISRM) Chevron-Bend (CB-) method. The fracture toughness describes the resistance of rock to fracturing. This parameter is therefore important when estimating the failure of rock and rock structures using rock fracture mechanics principles.
