Condition Monitoring for Fatigue — Implications of Fatigue Crack Shape
Condition monitoring for fatigue is often hampered by incomplete knowledge of crack dimensions; particularly penetration depth into the component. This paper discusses some generalizations made possible by results from a finite element technique which automatically predicts crack shape for planar cracks of initially general profile. Two specific examples are given: that of two interacting cracks and a practical case of a crack in industrial component where considerations of crack shape were able to assist in formulating a monitoring policy.
