FATIGUE LOAD CYCLE REDUCTION - D-G-D HYPOTHESIS

摘要

Reduction of complex load spectrum to test loads (which are applied during fatigue tests of machines, structure elements or material specimen) is a significant problem in fatigue analysis. The problem is particularly important, when results of tests (which are usually carried on with the simplified test spectrum often reduced to pulsating loads) are used for fatigue life's estimation. The D-G-D Load Reduction's Hypothesis is a new hypothesis presented in this paper.
