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.

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

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.

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

Fatigue Life Prediction of Microstructures
Volume 8: Mechanics of Solids, Structures and Fluids, 2012The formation and early growth of fatigue cracks in the high cycle fatigue regime is influenced by microstructuctural features such as grain size and morphological and crystallographic texture. However, most fatigue models do not predict the influence of the microstructure on early stages of crack formation, or they employ parameters that should be ...

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 ...

Fatigue life prediction of natural rubber: Effect of multiaxiality on the fatigue life reinforcement
2022Carbon Black filled Natural Rubber (CB-NR) is the most commonly used crystallizable elastomer for antivibratory applications in the automotive industry. For decades, uniaxial fatigue tests have been carried out for characterizing, understanding and modelling fatigue resistance of CB-NR.

Thermal fatigue life prediction
Materials Testing, 2004Abstract For clarifying the behavior of thermal fatigue and verifying the role of Coffin-Manson’s law in thermal fatigue, out-of phase type thermal fatigue tests were carried out on ferritic ductile cast iron. As a result of the tests, the dependence of thermal fatigue life and the plastic strain produced in each cycle on cyclic peak ...

Prediction of Tensile Fatigue Life for Unidirectional CFRP
Journal of Composite Materials, 2000Tensile fatigue strength in unidirectional CFRP depends on time and temperature as well as number of cycles. A prediction method of fatigue strength proposed [14] for polymer composites meeting certain conditions and confirmed for flexural fatigue strength of satin-woven CFRP laminates is applied to the tensile fatigue life of unidirectional CFRP.
