Some aspects of machine gun penetration of the aluminium sheet-metal plate using Ansys Autodyn
Original language description
The paper deals with numerical simulation, through the numerical code Ansys Autodyn v.11, of the penetration of 7.62-59 and 12.7-PZ32 bullets into a sheet metal plate. Fully clamped cylindrical plates are made of aluminium alloy D16AT used in aircraft structures. The thicknesses of the plates are from 0.6 to 2.5 mm. The paper presents material models used for the numerical system parts: both kind of bullets and the sheet metal. The simulation conditions are based on experiments, the results are comparedand influencing factors are discussed. Next the ballistic limit of the sheet metal is introduced in terms of an ultimate bullet velocity when no full perforation of the sheet metal occurs. The simulations provide some useful insight into the penetrationmechanisms. The results obtained can be useful in the analysis of the airframe structures with battle damage caused during war operations.
