Extending Steinberg’s Fatigue Method


Here is a paper for…

Extending Steinberg’s Fatigue Analysis of Electronics Equipment Methodology to a Full Relative Displacement vs. Cycles Curve



This paper also shows in a very roundabout way that “fatigue damage equivalence” between sine and random vibration occurs when the sine amplitude (zero-to-peak) is approximately equal to the random vibration 2-sigma amplitude.

Here is a Matlab script for cumulative damage index calculation, to be used after rainflow cycle counting:  RD_N.m

This script is for identifying individual points along the RD-N curve:  RD_N_point.m
