Abstract

This paper, based upon the nonclassical spherical shell theory, constructed a nonlinear line-spring model of work hardening material with Ramberg-Osgood constitutive relation for the elastic-plastic fracture analysis of surface cracked spherical pressure vessel, and calculated the elastic-plastic fracture parameters of the structure. The influences of inner pressure, crack shape, curvature of the vessel and material mechanical properties on the elastic-plastic fracture nature of the surface crack were studied as well. It was proved that the theoretical predictions of present model agreed well with experimental results.
