Abstract :
The paper presents the new finite element code LEGAK-DK for high performance computational developed in Russian Federal Nuclear Center VNIIEF and some numerical simulations results of the dynamic deformations of the air transport package, subjected to impacts at a high speed. Obtained residual deformed shapes are used to perform numerical analysis of the package´s thermal condition in fire. These simulations allow estimating on how a thermal resistance of the package can be reduced after high speed impacts. Comparison of the results with the experimental data shows that they are in a good agreement.
