Fatigue Life Estimates for a Notched Member in a Corrosive Environment (Corrosion)
type: CreativeWork
description: It is often assumed that the effects of an aggressive environment can be included in fatigue life estimation procedures by determining the material properties in the environment of interest. An analytical and experimental program was conducted to investigate this assumption. Automotive grade aluminum alloy 5454-H32 was selected for this study in laboratory air and 3% sodium chloride solution environments. A simple model where the total fatigue life is considered to be the sum of the portion where fatigue damage is best described by the notch strain field, and the portion where nominal stress and crack length dominate fatigue damage assessment, was used to estimate fatigue lives for center notched plate specimen.
