Compared to existing TBM performance prediction models, the current computational approach accounts for mixed ground conditions, different TBM and disc designs, as well as the direct coupling with wear models. The developed peridynamic model is thoroughly validated using several benchmarks, including indentation tests on sandstone specimens. Additionally, a full-scale Linear Cutting Machine (LCM) test conducted on Colorado Red granite is simulated, where cutting forces obtained from the computational model at various disc spacings are compared against experimental data. Excavation in mixed ground conditions, which can lead to excessive tool wear or failure due to rapidly changing cutting forces, was examined through an LCM experiment. Scaled-down peridynamic simulations show cutting force trends consistent with the LCM experiment results. Finally, to predict the influence of these varying cutting forces on tool life, an abrasive wear model is implemented in the peridynamic simulation framework.</div></td><td class='diff-marker'> </td><td style="background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;"><div>This paper presents the performance of a simulation tool based on state-based peridynamic theory, developed to model the interaction between cutting discs of a Tunnel Boring Machine (TBM) and the ground being excavated.
