Abstract
Modes of rolling contact fatigue failure are described and categorized for railway wheel treads and rims. The overall strength and endurance of railwa y wheels is investigated with special focus on material anisotropy and fati gue characteristics. An improved metallurgical design of the wheel material is proposed and tested. A procedure for defect-tolerant design of the whee l, addressing anisotropic fatigue properties, is outlined.
