Assessment of Influence Function for Elliptical Cracks Subjected to Uniform Tension and to Pure Bending

Source

A root mean square (RMS) type stress intensity factor, K, which is defined and used in [1] and [2] for crack growth and fracture calculations, is investigated in this study. Whereas the common K studies use approximate numerical integration of the influence function to analyze various configurations, in the present study the K definition is used analytically to derive accurate K values for various ellipticaljiracks subjected to uniform tensile stress and also to pure bending. The significance of these K results are explored via comparison with the exact classical maximum and minimum stress intensity factors along the front of the corresponding elliptical cracks.
