摘要：

An existing well established Weibull model for the statistical assessment of stress life fatigue data is shown to be applicable to the strain-life fatigue analysis, as an alternative to the classical Coffin-Manson approach with clear advantages. The model deals directly with the total strain without the need of separating its elastic and plastic strain components, provides an analytical statistical definition of the problem, and allows dealing with run-out data. Finally, an example of application is given to illustrate the method. (c) 2008 Elsevier B.V. All rights reserved.
