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.

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

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 ...

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 ...

Total Fatigue Life Prediction Methods
SAE Technical Paper Series, 1998<div class="htmlview paragraph">Two analytical methods of predicting the total fatigue life of a component such as weldment are compared: a relatively uncomplicated, two-stage, total-life-model known as the initiation-propagation or IP model; and a recently developed model termed the PICC-RICC crack growth model which integrates the effects of ...

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.

Fatigue of Composites—Fatigue Modulus Concept and Life Prediction
Journal of Composite Materials, 1986Fatigue behavior of glass fiber reinforced epoxy composite materials has been studied analytically. A new concept called "fatigue modulus," which is defined as a slope of applied stress and resultant strain at a specific cycle is introduced. Fatigue modulus degradation is studied using an assumption that the fatigue modulus degrada tion rate follows a
