A Study on the Fracture Mechanics of Support Structure of Excavation Puddle by LPG Explosion Using AUTODYN

Abstract:

Cutting iron bars using a gas cutting machine is indispensable inside puddles of pier foundations. However, gas explosive accidents constantly occur as a result of the leakage of gas. It is necessary to perform specialized and systematic evaluations on structural stability, such as internal stress of the support structure, because the structural stability dominates the explosion and the collapse possibility of the structure. In this study, a structure-fluid interaction analysis was performed using an explosion commercial program, 2D/3D AUTODYN, to apply engineering numerical analysis technology to analyze the fracture behavior. The structural stability of the supporting structure in puddles was evaluated.
