STUDY OF THE DEFECTS THAT ORIGINATE AND DEVELOP IN THE TREADS OF RAILROAD WHEELS DURING SERVICE
Mechanism theories for the formation of defects that originate and develop in the treads of railroad wheels during service are presented. These defects were classified after a study of wheels that developed these defects during service and of wheels that were subjected to simulated service tests on a wheel-testing dynamometer. At least two general types of defects were found to occur during service-defects caused by stresses developed by braking and defects caused by stresses imposed by rolling loads.
