NUMERICAL AND EXPERIMENTAL STUDY OF DESTRUCTION OF METAL PIPES THROUGH USE OF HIGH EXPLOSIVE

摘要

Various liquids are commonly transported through metal pipes. For reasons of safety it is important to understand the behavior of pipes when subject to an explosive loading from within. This research paper is concerned with examining the expansion and destruction of metal pipes subjected to a high power explosion by high explosive. An experimental study was carried out for this research and visualized using high-speed camera images. Results were then compared to a computer simulation of the same problem. Numerical simulations are performed in three dimensions using the LS-DYNA code. Results obtained numerically compared well to those from experiment.
