Effects of Weld Zone Properties on Burst Pressures and Failure Locations


Abstract: The effects of weld zone properties on the burst pressures and burst failure locations of DOT-39 nonrefillable refrigerant cylinders were examined using the finite element analysis (FEA) approach. In order to do this, the weld zone properties were specified from the manufactured cylinders. In the computer modeling process, these cylinders were subjected to an incremental internal pressure within the material nonlinear field. The results, compared with corresponding experimental results, show that weld zone properties play an important role in determining the burst pressures and the failure locations of these cylinders.
