Transverse Defect

An approximate analysis of the shell/transverse defect growth in steel rails during use is presented. A general solution for a single subsurface crack is presented first. A simpler approach, which considers the transverse defect alone, is examined as well. Residual stresses are included by introducing their stress distributions mechanically. A proposed mixed-mode loading growth law is used for fatigue life calculations and the crack length versus life curves are obtained. The life of the shell/transverse defect is found to be much shorter than that of the single transverse defect.

This review paper discusses the basic problems related to the use of cohesive models to simulate the initiation and development of failure in various types of engineering issues. The most commonly used cohesive zone models (CZMs) are described. Recent achievements in the field of cohesive modeling are characterized, with particular emphasis on the problem of mixed mode loading, the influence of the strain rate, the stress state triaxiality, and fatigue. A separate chapter of the work is devoted to the identification of cohesive parameters. Examples of the use of CZMs for the analysis of the fracture and failure process in various applications, both on the macro and microscopic scale, are given. The directions of CZMs development were indicated as well as the issues that are currently under particularly intensive development.
