摘要：

Stresses around a material defect in the rim of a railway wheel are studied during sequences of over-rolling contacts using elasto-plastic finite element analysis. Results in the form of animations show a complex evolution of the stress field. Based on multi-parametric studies, conclusions of practical interest to railway engineers are drawn. Insights into the physical process have been gained. (C) 2002 Elsevier Science B.V. All rights reserved.
