It is crucial to assess the
dynamic behavior of structures exposed to blast loading in order to improve the
integrity and survivability. Numerical simulations are widely used to predict
the response of structures under blast loading. A commercial nonlinear finite
element code, LS-DYNA provides three blast loading methods: Empirical blast
modeling technique CONWEP, Arbitrary Lagrangian Eulerian technique (ALE), and
hybrid CONWEP - ALE technique. In this study, an experimental testing of a flat
plate subjected to blast loading is modeled using these three blast loading
methods in LS-DYNA. Mesh resolution study of ALE formulation is conducted to
determine the influence of element mesh size on predicting blast loading
effects that is converted through fluid structure interaction algorithm from
Eulerian to Lagrangian type of elements. It is drawn a comparison between peak
pressures calculated in simulations and maximum dynamic deformation measured in
the field test. Finally, the discussion and conclusion are provided.
