Numerical Failure Analysis and Fatigue Life Prediction of Shield Machine Cutterhead

Numerical Failure Analysis and Fatigue Life Prediction of Shield Machine Cutterhead

This paper presents numerical failure analysis on cracking of shield machine cutterhead structure during a metro-tunnel construction. The stress intensity factors (SIFs) of surface cracks with different shapes and location angles were analyzed by a finite element simulation method based on linear el...
