... using only crack-growth-rate data. Research on small-crack behavior and improved analysis methods have shown that fatigue is “crack propagation” from microstructural discontinuities in a number of engineered materials, such as aluminum alloys, titanium alloys and steels [( 7 8 9 10 11 )]. Large...
