Numerical investigation of TBM disc cutter cutting on microwave-treated basalt with an unrelieved model

Cutter wear or damage is a significant issue during tunnel boring machine (TBM) tunneling in hard rock. Microwave preconditioning has been verified as a promising approach to reduce cutter wear and enhance the TBM excavation efficiency. Thus, understanding the TBM cutting performance for microwave-t...
