摘要
The behavior of a blast proof door under a blast load was investigated experimentally and analytically An experiment was carried out to study the behavior of the blast proof door induced by explosive detonation. Subsequently, a finite element analysis was performed using the Lagrangian and Arbitrary Lagrangian Eulerian methods for comparison with the experimental results. The experimental results indicated that the blast proof door was bent due to the blast wave induced by the explosion, and an elliptical opening was formed on it. This study demonstrated that the Arbitrary Lagrangian Eulerian method is a better predictor for the detailed shape of the blast proof door after an explosion, while the Lagrangian method is a better predictor at the tearing of the boundary between the blast proof door and the splice. It was further noted that the overall deformation of the blast proof door using the Lagrangian method is more significant than that elicited using the Arbitrary Lagrangian Eulerian method.
