Influence of wheel out‐of‐roundness on the remaining life of railway wheels under mixed‐mode fatigue loading

As a common condition in train operation, the out‐of‐roundness (OOR) of wheels may have a great influence on the life of cracked wheels. In this study, the I–II mixed‐mode crack growth rate of different angles was tested, finite element analysis was carried out by using the test results, and the inf...
