ABSTRACT. THIS PAPER DESCRIBES AN ANALYTICAL MODEL USED TO ESTIMATE THE DISPERSION ASSOCIATED TO THE DETERMINATION OF THE FATIGUE DAMAGE CAUSED BY RANDOM SOURCES WHICH ARE ALWAYS PRESENT AT TYPICAL STRESS LOADING PROCESSES. BASED ON THE MODEL, IT IS POSSIBLE TO SHOW THAT THE DISPERSION OF DAMAGE PREVISION IS PROPORTIONAL TO THE SQUARE ROOT OF THE ACQUISITION TIME. THIS CONCLUSION ALLOWS THE DEVELOPMENT OF SIMPLE TOOL WHICH CAN BE USED TO ESTIMATE THE DATA ACQUISITION TIME SPENT IN AN EXPERIMENTAL PROGRAM IN ORDER TO FURNISH RELIABLE ANSWERS.
KEYWORDS : FATIGUE LIFE PREDICTION, RANDOM LOADING, RELIABILITY
