The Effect on Cutting Tool Forces of Pre-Weakening a Rock Surface by Waterjet Kerfing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Empirical models are developed to describe the influence on the cutting process of preweakening a rock, by cutting a series of parallel kerfs in the surface with high pressure waterjets, prior ...
Rock Properties and Their Effect on Thermally Induced Displacements and Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A discussion is given of the importance of material properties in the finite-element calculations for thermally induced displacements and stresses resulting from a heating experiment in an in-situ ...
A Review of Jet Assisted Rock Cutting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High volume, low pressure water jets have been employed for erosion of loosely consolidated rocks for centuries and this excavation method finds application in specialized circumstances even ...
