Abstract

This paper discusses application of the boundary element method (BEM) to the initial stress of a sprocket used as a coupling for an engine laboratory dynamometer. Initial visual evaluations indicate the failure initiated in a slot key groove in the hub of the sprocket. The boundary element method, using BEASY, has been used to perform an initial, two-dimensional stress of the sprocket to evaluate the overall affect of the stress concentrations of the key slot. Additional work has been initiated to extend the work of this paper to three-dimensional models which will evaluate effects of other defects noted during a separate failure analysis of the s
