This post gives info on random vibration fatigue simulations. What is a Random Vibration Fatigue simulation Random vibration fatigue is a mechanical analysis technique used to assess the durability of a structure or… Continue reading
In random vibration fatigue FEA (Finite Element Analysis) simulations, the following statistical parameters are among the most important for characterizing the loading conditions and assessing fatigue damage: These statistical parameters are central to… Continue reading
When dealing with practical fatigue calculations, we simplify a lot in order to make calculations easier. Fatigue by itself is a complicated and stochastic process and it is wise to adopt easy and… Continue reading
Let;s take as an example the following SN curve. The different regions that are highlighted are the following: The High Cycle Fatigue ( Stress Life or SN method or Nominal Stress Approach) is… Continue reading
