Pagination or Media Count:
In the previous study of first order models with 8 response variables to predict fatigue life in elastic range under random vibrations, 4 variables showed significant effects. In this part of the research both first and second order models of these 4 significant variables based on 10, 18, and 24 tests are developed. The tables of analysis of variance, and of predicted lives together with their residuals and 95 confidence intervals are constructed for each of the first and second order models. Author
