Opening mode stress intensity factors are determined using point matching for two diametrically opposed radial cracks at a hole in a rectangular sheet v/here the cracks lie along the line of the minimum section. The sheet is subjected to either a biaxial stress on its edge or a pressure distribution

The optical method of photoelasticity was used to measure stress intensity factors of cracks in stringer stiffened structures. From a photoelastic material L-shaped stringers and plates with central holes were manufactured, and one stringer was attached vertically to one side of each plate by means
A calculation procedure for plates with semi-elliptical surface cracks under tension and bending with aspect ratios of d c 5 0.2 and arbitrary relative crack depths d t is presented. For the computation an improved line spring model is used. K,-values are calculated along the crack contour. For the
This paper presents the calculation of stress intensity factor (K) solutions for surface cracks in the thread ground of bolts subjected to axial loading directly applied by the nut. The stress-strain computations have been done by means of the finite element method with quarter-point singular isopar
