Fracture control has been one of the Energy Pipeline CRC flagship research areas, with strong international recognition.
Researchers at the University of Wollongong focussed on:
• New methods for fracture control in small diameter natural gas and other energy fluid pipelines;
• Accurate numerical models of Fluid-Structure Interaction (FSI) during running ductile fracture as an alternative to full-scale testing; and
• New improved fracture velocity model that incorporates the effect of the material ductility (Y/T ratio) on the fracture propagation velocity.
The EPDECOM fracture arrest software was one of the significant outcomes of this research. EPDECOM is a modern fracture control application for the control of running ductile fracture integrating a gas decompression model and a fracture propagation model to estimate the minimum required toughness based on the Battelle Two-Curve Method.
