Abstract [en]

In this work, the finite element method is employed to gain an understanding of the behaviour of a cracked bridge roller bearing in service. The cracked roller is considered as an edge-cracked disk (two-dimensional plane strain system) subjected to a radial compressive line load. The crack parameters KI and KII are calculated for the relevant load configuration and angle of disk rotation. The calculated data are also used to check the accuracy of approximate SIF solutions reported earlier [1] and [2]. For plain Mode I loading very good agreement is found between the obtained results and data presented in Schindler and Morf (1994).
