DEVELOPMENT OF RANDOMIZED LOAD SEQUENCES WITH TRANSITION PROBABILITIES BASED ON A MARKOV PROCESS.

Abstract

Because of the controversial nature of the reliability of cumulative damage rules, fatigue life estimates of aircraft structures and components, subjected to variable amplitude service loads, are presently based on programmed fatigue tests. The most frequently utilized load sequences--up, down, up-and-down, and randomized steps-are either unrealistic or difficult to apply in testing machines. A time series combining the advantages of both randomized and programmed sequences while avoiding the disadvantages of both was presented based on the mathematical model of a Markov chain. (Author)
