Description
Summary:This report deals with the cutting of rock and other brittle materials by means of indentation tools. The principles of identation cutters are dealt with at length, the coverage including elastic contact stresses for initial loading by various types of indenters, application of formal plasticity theory to penetration analysis, and a variety of theories and penetration analyses that are not based on plasticity theory. Practical indentation mechanisms are described, and theoretical analyses are given for the dynamics and energetics of various types of roller cutters. The final section reviews experimental investigations and results for rock-cutting discs, giving a systematic summary of available data. (Author) See also Part 6, AD-A045 127.
