Abstract In order to evaluate the blast mitigation effect of polyurethane foam in cylindrical explosion containment
vessels (CECVs), a three-dimensional numerical simulation model was established. The Structured Arbitrary
Lagrange-Euler (S-ALE) algorithm was applied in current simulations to define the coupling contact
between TNT and Lagrange algorithm. The numerical model was verified by comparing the dynamic
deformation and permanent deformation of the experiments. Based on the numerical simulation model after
verification, the influence of polyurethane foam filling inside CECVs on the mitigation effect was
investigated. The results revealed that compared with the ALE algorithm, the numerical simulations based
on the S-ALE algorithm… More >
