Experimental investigation of fatigue damage accumulation

Abstract

IN 1945, M. A. Miner presented his approach for cumulative damage in metal fatigue to the American Society of Mechanical Engineers. In this approach, the expended life of a specimen is defined to be equal to the summation of the number of cycles that are applied at each different stress level when expressed as a percentage of the number of cycles that would cause failure. The Miner approach is mathematically expressed as shown in equation (1).
