dc.description.abstractOne of the most important problems of hard rock cutting machines is machines are able to cut the rocks having strength up to a certain value (e.g. 250MPa) with very high energy costs. This study will find applications in many engineering areas such as mining, tunnelling and drilling etc. This research focuses on 'fatigue of rock/granular material' and its technical application in hard rock cutting machinery and mining. Oscillating Disc Cutting (ODC) - Australia technology has been developed with the latest technology in this field in the world and is capable of breaking very hard rock, with strength up to 350MPa, at acceptable-to-good excavation rates by using 70% less cutting forces and energy compared with the standard hard rock cutting machines. Of course there are many rock cutting parameters including machine parameters such as attack angle of cutters and torque values etc. and rock parameters such as rock strength and brittleness etc. However, this research just focuses on the behaviour of the rock-tool interaction zone under various cyclic loading types. Research results showed the developed Fracture Process Zone (FPZ) under cyclic loading is much bigger than the FPZ developed under monotonic loading even with the use of lower forces.
