Learn More about Material Fatigue

Metal fatigue is a complex subject. The failure of a structure due to fatigue seems often random and hard to predict. The fatigue process is stochastic by nature and can therefore only be described by statistical models. Although the physical processes driving fatigue are quite complicated and still not fully understood by science, metal fatigue can be rather accurately calculated and predicted in practice, if a number of design rules and assumptions are taken into account.
We like to share our knowledge with you, so you can obtain a better insight in the nature of fatigue and the process of fatigue analysis and learn how to avoid costs by developing more durable products.
