Assessment of the fatigue life of machine components under service loading a review of selected problems

Włodzimierz Będkowski

Based on a literature review, the author provides a historical outline of the fatigue analysis and describes the current trends aiming at comprehension of the fatigue life of engineering structures under service loading. Next, an algorithm for multiaxial fatigue life prediction is identified, describing steps of calculation. Classification criteria of fatigue failure and components of the stress state in multiaxial loading conditions are also presented; recognising the importance of the so-called Standarised Load Histories (SLH) used in the comparative analysis of fatigue life of finished products.
