Abstract
This paper proposes a mechanism for surface crack initiation in rolling contact elements; it is based on the assumption that ductility exhaustion of the immediate surface layer takes place due to the incremental accumulation of surface plastic deformation. This deformation pattern is related to the nature of the combined compression-shear loading acting on the contact zone. An experimental technique employing a new design of biaxial specimen and loading apparatus has been developed and used to quantify empirically the features of the flow process leading to crack initiation. Results of the study are discussed in relation to failure characteristics of the railhead. © 1988.
