Analytical and Experimental Study on the Thickness Effect to Fatigue Strength (1st Report - Results of Fundamental Specimens)

摘要

Thickness effect is known as a weakening factor in fatigue strength.However, sufficient knowledge is still unavailable with regard to whatfactors are dominating such thickness effect and also how the differentstructural or joint types or different loading patterns influence suchthickness effect. In this paper, the results of fundamental experimentare shown in combination with the associated finite element analysis.Some observations are demonstrated to clearly thickness effect, andbased on the observations, preliminary proposal of the method toestimate thickness effect was derived.
