Cycle Counting in Fatigue Analysis — Benchmark

Application ID: 14519

A benchmark model of the Rainflow counting algorithm compares results between ASTM and COMSOL fatigue module using a flat tensile test specimen. An extension is made for the cumulative damage calculation following the Palmgren-Miner model and results are compared with analytical expressions.

This model example illustrates applications of this type that would nominally be built using the following products:
