How Many Specimens? An Aid in the Design of Fatigue Test Programs

Abstract

Increasing fatigue test sample sizes increases the accuracy with which population statistics may be calculated and increases the sensitivity of tests comparing different groups of results, but it also increases testing costs. Information is presented which will aid the designer of a fatigue test program in deciding sample sizes.
