Crack propagation simulation and remaining life assessment of freight wheel with web hole

Last updated on 28 March 2013 5:18

Typical fatigue cracks at wheel web holes propagate under a combination of mechanical forces and braking thermal loads. The stress intensity factors (SIF) for different crack sizes are calculated using the approach of 1/4 node displacement and sub-model techniques. Models on fatigue crack propagation and remaining life prediction are presented...
