This paper presents a new compendium of Stress Intensity Factors for internal defects in tubes and plates, obtained through finite element analysis using CASTEM 2000. Three configurations are considered: Circumferential internal semi-elliptical defects in tubes (163 cases), Axi-symmetrical internal defects in tubes (42 cases), Semi-elliptical surface defects in plates (30 cases). The parametric meshes used, as well as the validation of the results, are both presented in this paper. Finally, the results are given in tables, along with a graphic representation of their evolution as a function of geometrical parameters.
