Material Property (m) can be calculated based on repeated test runs. The steps include:
-
- Enter statistical information, Grms and Time or Cycles to Failure
- Plot Grms vs time (or cycles) on log-log plot
- Create trendline (power law function)
- Calculate slop of the power law function trendline (b)
- Calculate m
Where:
m = (-(1/b)*80% for random waveforms
m =(-(1.b)*60% for sinusoidal waveforms
