Abstract

Numerical simulation emerges as a highly effective method for studying the interaction between structures and blast waves. In this study, we apply a multi-material arbitrary Lagrangian-Eulerian method to explore the dynamic response of a reinforced concrete slab under explosion load. The Arbitrary Lagrangian-Eulerian method is a finite element method in fluid and solid mechanics to simulate complicated interactions of solids and fluids. The numerical model is validated by comparing the maximum reflected pressure and mid-span deflection with the results from blast experiments on reinforced concrete slab. In addition, damage patterns in the slab are analyzed using the validated model. This effective modeling technique will be highly useful in the design of infrastructure to enhance blast resistance.
