Corrosion Fatigue Cooperative Testing Program Statistical Analysis.
Abstract
Corrosion fatigue tests were conducted on aluminum alloy specimens for the AGARD-Coordinated Corrosion Fatigue Cooperative Testing Program by nine different laboratories. A statistical analysis of the resulting experimental data was performed to establish whether fatigue test results were reproducible from one laboratory to another and to examine the effect of environmental condition on fatigue life. Three different statistical methods were applied to the data, one of which involved using a computer program. The analysis showed that there are several significant inter-laboratory differences and that environmental condition affects life, significantly and consistently, and the origin of fatigue in specimens. Additional keywords: Analysis of variance, Least significant difference test; Chi-square test of independence. (Author)
