Abstract
Fatigue tests have been carried out on mild-steel specimens 10-in. wide by 0·3-in. and 1·0-in. thick. Each specimen contained a small central slit to initiate fatigue cracks and measurements of crack length were taken throughout the test. Comparison of the results with those obtained previously on 0·128-in. thick specimens (Frost and Dugdale (I)‡) showed that, for a given loading cycle and crack length, the rate of growth was independent of specimen thickness.Keywords
