ANSI/AGMA 2001 -B88, Appendix B presents the fundamental method for evaluating Miner’s Rule. To analyze the
load spectrum, stress values are calculated for a given load and then modifiled using“K or“C”factors. When computing
the stesses for other points, the stress values are usually simply ratioed rather than recomputing the stresses using new
“K” and“C”for each point. In this paper, the effect of using a dynamic and load distribution factor for each load point is
evaluated and compared with the simple ratioing approach, Comparisons are made for anumber of aircraft histograms as
shown in AGMA 911 A94 along with a commercial ground application.
