Rainflow algorithm is one of the widely accepted techniques of cycle counting in fatigue analysis for damage assessment in engineering components and structures. In this paper a brief summary of Rainflow cycle counting technique has been outlined. To demonstrate the efficacy of the developed Rainflow algorithm in a computer is being validated by numerous standard set of test problems simple sequences are described. An attempt has been made to illustrate the algorithm accuracy by demonstrating a number of simple examples. The examples that are included are (i) Available literature sequences, (ii) Decreasing amplitude sequence (iii) Increasing amplitude sequence and (iv) Constant amplitude sequence. Finally the results from analyzing a service load spectrum of a fighter aircraft is provided in this paper.
