Fatigue Response of a Random Non-Proportional Load

Application ID: 2201


A frame with a central cutout is subjected to a random load consisting of 1000 load events. The external load, recorded using three strain gauges, is simulated using superposition of three unit loads. The stress state around the cutout is obtained with the Rainflow cycle counting algorithm. The damage is estimated using the Palmgren-Miner linear damage rule.
