NUMERICAL SIMULATION AND REGRESSION-BASED PREDICTION OF ROTARY DISC CUTTER FORCES IN TBM ROCK CUTTING
This study introduces a computational framework for estimating disc cutter forces during rotary cutting in Tunnel Boring Machines (TBMs), combining LS‑DYNA with a Smoothed Particle Galerkin (SPG) approach and the Riedel–Hiermaier–Thoma (RHT) material model. A total of 58 simulations were performed to examine how cutter...
