Fatigue life prediction of ceramic-matrix composites
Aircraft Engineering and Aerospace Technology, 2018Purpose This paper aims to predict fatigue life and fatigue limit of fiber-reinforced ceramic-matrix composites (CMCs) with different fiber preforms, i.e. unidirectional, cross-ply, 2D-, 2.5D- and 3D-woven, at room and elevated temperatures. Design/methodology/approach Under cyclic loading, matrix multicracking and interface debonding occur upon ...

Fatigue Life Prediction of Structures
1994Fatigue life prediction problems are discussed from the viewpoint of probabilistic mechanics of solids and structures. A survey of random factors in damage and fracture is presented with a special emphasis on the statistical scatter of mechanical properties of materials and/or structural components.

A Note on Fatigue Scatter and Life Predictions
1980One of the major problems in predicting fatigue life for service components from laboratory data is that the scatter of laboratory data often differs from that of actual service components. In this note a method to estimate fatigue lives from crack propagation models is presented.

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 ...

Fatigue and Life Prediction of Gears
1996AbstractThis article summarizes the various kinds of gear wear, including fatigue, impact fracture, wear, and stress rupture, describes how gear life in service is estimated. It presents the rules concerning lubricants in designing gearing and analyzing failures of gears. The article presents the equations for determining surface durability and life of

Bayesian Fatigue Life Prediction
1985Fatigue failure is an important failure mode for offshore structural joints, in particular for dynamically sensitive deep water structures. To predict the fatigue life only a few test results are generally available for the actual type of joint. In addition, however, test results for joints with slightly different geometries are available. Fatigue life

Predicting the total fatigue life in metals
International Journal of Fatigue, 2009Abstract When a metal specimen is subjected to cyclic loading, a large number of initiated cracks will initiate in its volume. The specimen forms a sample of initial cracks: the larger specimen, the larger is the sample. In previous work of the author it was shown that the fatigue limit can be predicted by estimating the largest expectable crack ...

Prediction of the fatigue life of pneumatic tires
Journal of Machinery Manufacture and Reliability, 2010A method of the prediction of the fatigue life for parts of pneumatic tires based on the computation of the stress-strain state of the stress concentration areas in a rubber matrix and the self-heating temperature by means of the finite-element method and experimental fatigue curves for rubbercord composites has been developed.
