Determination of Small Crack Stress Intensity Factors for an American Society for Testing Materials (ASTM) Middle Tension Test Specimen by Finite Element Method

Abstract

Improved small-crack stress intensity factors are important for accurate fatigue crack growth prediction. This report presents accurate small-crack stress intensity factor distributions for the American Society for Testing Materials middle tension test specimen, derived in three dimensions utilising the advanced finite element method code StressCheck for a parametric study of a range of small crack sizes and shapes. This information was not readily available in reference books. The results have been presented in tabulated normalised form for future reference and clearly show the influence of the specimen notch on the variation of stress intensity factors.
