Benchmark Problems in Multiaxial Fatigue
Last modified: 2015-02-05
Abstract
Fatigue analysis software packages range from the simplest to most complex both in terms of fatigue theories and material properties. In this paper, several of these commercial packages are employed to reanalyze a benchmark dataset reported at the first multiaxial fatigue symposium held in 1982. Surprisingly, our calculations show that all of the software evaluated gives about the same results. Even more surprising we found that the modern fatigue software was no better than the calculations done 30 years ago. But today, an inexperienced first year graduate student can use modern software to produce the same quality of fatigue assessment as an experienced PhD student 30 years ago.
