Characteristics of the crack tip field in high-speed railway tunnel linings under train-induced aerodynamic shockwaves

Underground Space
High-speed railway tunnels in various countries have continuously reported accidents of vault falling concrete blocks. Once the concrete block falling occurs, serious consequences follow, and traffic safety may be endangered.

Research on structural fatigue residual life of pitch bearing rings after pre-damage

Jixie chuandong
ObjectiveThe corrosion fatigue fracture of the wind turbine pitch bearing is a major failure mode, often leading to the blade detachment and shutdown. To this end, a finite element model of replacing the whole pitch bearing with a local one was proposed ...
