Plate Response to Buried Charge Explosion

Abstract:

Article Preview

This paper deals with the dynamic response of clamped plate to the loading following from the detonation of buried explosive charge. The cylindrical explosive charges of 8 kg mass has been considered. The numerical analysis is carried out using the LS DYNA finite element code. Numerical results exhibit reasonable agreement with results of controlled explosion experiments. The study is oriented mainly on the effects of structure representations (solids or shells) and of computational mesh size on evaluation of the structure response.
