Cyclic Deformation and Fatigue Analysis for Notched Components.

摘要

The design of cyclically loaded members - an area of major concern to design engineers - ss a complex iterative process fraught with uncertainty. At present the effect of factors such as geometric discontinuities is not completely understood and the evolution of a fatigue resistant structure from an initial design based largely on experience and empiricism is accompanied by extensive reliability testing. This design process, although effective, is expensive and time consuming. Therefore, several authors have sought analytic procedures which model the fatigue process in terms of a deterministic mathematical description.
