Abstract

By establishing cylinder pressure vessel with a crack model, this paper presents the similarities and differences of semi-ellipse crack method and arbitrary method of 3-D fracture analysis based on finite element software ANSYS Workbench to explore the effect for the whole structure and single-crack results of the two methods. By establishing a model with a crack, importing the model to analysis environment and analyzing results compare the two method effect for pressure vessel wholly. From stress distribution, structural deformation and stress intensity factor distribution results indicate that numerical values on structural deformation and stress intensity factor of the two methods are nearly equal and the gap on stress value is large and the stress result of semi-ellipse crack fracture method is more conservative for the structural assessment.
