Structural Safety, 1989
Abstract Fuzzy set theory is used to encode system uncertainty in a structural reliability analysis. The fatigue failure for joints is described by the common empirical relationship between the applied stress and the corresponding number of stress cycles resulting in a failure.

The prediction of implement fatigue life
Journal of Agricultural Engineering Research, 1989Abstract Estimates of implement fatigue life are needed to avoid failure without excessive weight and cost. Life under complex loading can be predicted by computer analysis of the elasto-plastic stress-strain behaviour in conjunction with a cumulative damage law.

Journal of Applied Physics, 1960
On the basis of the relation between the ``reliability-function'' (probability of surviving beyond age N in cycles or t in time) and the ``risk'' of failure (as a function of age), the physical interpretation of the latter can be used to extrapolate the former beyond the range of possible observation.

Methodologies for predicting fatigue life
JOM, 1997This article reviews the basic techniques employed in fatigue life prediction. The stress-life, local-strain, and fracture-mechanics methods as applied to life prediction under constant amplitude loading and variable amplitude loading are discussed. Life prediction methodology under variable maplitude loading is also discussed, with particular emphasis

An Approach for Fatigue Life Prediction
Volume 6: Materials and Fabrication, 2005Fatigue damage is generally described as the nucleation and growth of cracks to final failure. These two stages of fatigue damage are often modeled with completely different methods with no quantitative relationships between them. In addition, a number of fitting parameters are needed in order to consider different effects. The current work is aimed to

Abstract This chapter summarizes the various kinds of gear wear and failure and how gear life in service is estimated and discusses the kinds of flaws in material that may lead to premature gear fatigue failure. The topics covered are alignment, gear tooth, surface durability and breakage of gear tooth, life determined by contact stress ...
