title = "Numerical investigation of aluminium plates subjected to blast loading using arbitrary lagrangian eulerian and lagrangian approaches",
abstract = "This paper deals with the non-linear dynamic behavior of thin Aluminium plates subjected to blast loading. Aluminium plates with grade EN AW-1050A-H24 are studied. The square specimens have an area of interest of 300*300mm2 and a thickness of 2.5mm. The blast loading is generated using free air blast (FAB) and explosive driven shock tube (EDST). A numerical finite element model (FEM) using the commercial software LS-DYNA is developed and validated based on the experimental data from literature. A failure model is combined with the modified Johnson-Cook constitutive relation to study the dynamic failure on the target. A comparative study between the arbitrary Lagrangian Eulerian (ALE) and the Lagrangian approach is assessed to guarantee the most adequate formulation for the numerical model. The out of plane displacement from the ALE simulations were found to be in good agreement with both the experimental values and the corresponding results from the Lagrangian simulations. In this paper, an effort is made to present a detailed numerical model for the prediction of the nonlinear dynamic behavior of Aluminium plates subjected to blast loading.",
