A Formalism to Model Environment-Sensitive Fatigue Crack Growth

Last modified: 2013-02-10


The paper deals with the effect of 3.5% NaCl solution on long fatigue crackgrowth in the thin sheet wrought aluminium alloy 6013 T6. A formalism aimed to provide aquantitative model of the environmental effect is summarized and extended. The formalismis essentially based on the concept of a rate-controlling step and the application of themethod of dimensional analysis to the individual steps. The sensitivity of the resultingmodel to distinct modifications of the underlying assumptions is discussed.
