Fatigue crack growth (FCG) show the structures is significantly dependent on bulk material properties that attend as nucleation locations for fatigue crack growth (FCG). It is hard to classify a FC in the structures through service. The main objective of this work is to evolve rainflow counting methods to generate vertically descending variable load to predict the fatigue life (FL) and FCG ratr based on fatigue crack test. To achieve the objective, three-point bend specimens were used for the experiments, simulation and prediction using ASTM A533 steel alloy according to the ASTM E647-00 standard. The expected results show that most of the fatigue models have a different background and not capable of representing all factors affecting the fatigue life.
