Abstract

Fracture tests were performed on 10 structural steel tubes with circular hole. Test results indicate that crack initiate at the edge of the hole and propagate perpendicularly to loading direction. The initial crack come into being earlier with the magnification of the radius of the hole. Tubes with two holes behave more ductile than those with one hole. The numerical procedure implemented the generalized hydrostatic yield model through the parametric design language (APDL) together with the User Programmable Features (UPFs) available in the general-purpose finite element package ANSYS. Numerical simulation results verify the precision of the generalized yield model and the validity of the subroutine. Numerical analysis results of the structural steel tubes with hole show that metal ellipsoidal fracture model could successfully predict the first crack of the steel tubes with circular holes.
