Periodical/Journal: CRREL Report 80-21
Abstract: This report deals with the cutting of rock and other brittle materials by means of indentation tools, The principles of indentation 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. Practical indentation mechanisms are described, and theoretical analyses are given for the dynamics and enegetics 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.
