Procedure of residual fatigue lifetime assesment of railway axle
Scholz, David ; Seitl, Stanislav (referee) ; Náhlík, Luboš (advisor)
The goal of the bachelor's thesis is to present options to calculate residual life of a railway axle from more sophisticated points of view. These methods are requested by railway operators to ensure higher safety of train traffic. The main issue is the perspective of fracture mechanic, considering railway axle as a component with an initial crack or other defect. The theoretical part deals with basic definitions of fracture mechanics and processes describing crack propagation, using conception of stress intensity factor, which is the most used nowadays. Following part also describes a fatique life estimation process in real. This process is demon-strated using an example after that.
