Fracture Toughness Testing of Rock: Part 2 of Lectures at the CISM in Udine, Italy, July 5-9, 1982

摘要

The report has three sections. The first one is condensed from a recently published review on the fracture toughness testing of rock. The second section summarizes experimental and analytical work performed to develop core bend specimens. The last and largest section presents experimental work with the aim of obtaining representative fracture toughness values from these specimens. Part of this section was recently published but most of its material is new and more is in progress. The conclusions drawn from the core toughness data are therefore somewhat incomplete.
