WebStress based fatigue analysis is essentially a linear technique, and only provides accurate results when a component has a long life (otherwise known as High Cycle Fatigue). Web22 Jul 2024 · The most useful results when drawing conclusions from random response fatigue analysis are the damage values. This is an indication of whether the system is susceptible to fatigue failure. These numbers are based on the fatigue curve of the material, the number of stress cycles seen by the material, and the amplitude of the stress cycles.
