Article Abstract

[This abstract is based on the author�s abstract.] A methodology is proposed for designing life tests based on the random fatigue-limit model (RFLM) that describes the relationship between fatigue life and the applied load in the presence of fatigue limits. Optional test plan criteria are considered to suit the needs of the practitioner. Equivalence theorems used to verify optimality of test plans are presented. The methods are illustrated using a nickel-base superalloy experiment.
