A mathematical model of fatigue crack propagation based on the crack closure concept is proposed. It allows prediction of fatigue crack growth under complex loading sequences on the basis of data obtained under constant amplitude and simple High-Low, Low-High loading sequences. The model explains th

This paper discusses an approach for the fatigue analysis of spot-welded joints under variable amplitude load:ng. Two simplified relations, relating the nugget maximum load and metal thickness to the fatigue life of an entire durability schedule, are developed. A computer program is also developed,

The fatigue crack growth (FCG) behavior of 7075-T651 aluminum alloy was studied under constant and variable amplitude loadings in vacuum, air and 1% NaCl solution. In the study of constant amplitude loading fatigue, the stress ratios were 0.1 and 0.85 and the loading frequency was 10 Hz. In the stud
