A Short-Rod Based System for Fracture Toughness Testing of Rock

Source

A system for fracture toughness determination of rock using a short-rod specimen is described and evaluated. The calibration of the specimen by finite-element analysis for two loading cases is reviewed. A description of the preparation procedure is given showing the practicality of the testing system. Verification of the system is accomplished through testing of polystyrene, Indian limestone, and Westerly granite. The results from these tests compare favorably to fracture toughnesses measured by other more expensive and time consuming methods.
