Comparison of BTC, RBTC and HLP Models in the Calculation of the Dynamic Ductile Fracture Propagation Velocities Based on the X80 Full-Scale Burst Test

Many efforts have been paid to solve the running ductile fracture (RDF) arrest issue in the gas pipeline since RDF could cause a serious disaster. Battelle two-curve model (BTCM), reformulated BTCM (RBTCM) and HLP Model (HLPM) seem to be the promising way to solve the RDF arrest issue. In order to clarify the validity of BTCM, RBTCM and HLPM in the calculation of RDF velocity for Chinese modern X80 pipes, a full scale burst test was carried out. And, the RDF velocities were calculated based on BTCM, RBTCM, and HLPM, respectively. By comparing the calculation results with the experimental ones, it was found that the RBTCM shows the best fitting with the experimental results. The possible reasons were discussed in this Paper.
