[en] The objective of this paper is to present the results for stress-intensity factors (SIF) directly computed through a three-dimensional, embedded singularity, hybrid-displacement finite element procedure, for semi-elliptical cracks, of various geometries, located at the outer or inner surfaces of pressurized or thermally shocked thick walled cylinders. Due to length limitation, the paper contains SIF solutions for pressurized cylinders of inner to outer diameter ratios of 4:5,2:3 and 1:2, with pressurized and unpressurized inner semi-elliptical cracks of aspect ratios (b/a=1,2 and.5), at crack depth of b/h=.5 and .8; and with outer semi-elliptical flaws of similar geometries. Results for the above crack geometries in thermally-shocked cylinders are also discussed. (Auth.)
