Ballistic resistance of the transport airplane fuselage to impact of 9mm action 5 pistol bullet

20th SVSFEM ANSYS Users' Group Meeting and Conference 2012. – 18 p.The article presents an experimental and numerical approach to estimate ballistic limits of the pistol hollow point bullet Action 5 penetrating the target representing the transport airplane fuselage. The target containing the composite sidewall, the insulation glass wool layer and the duralumin skin plate is penetrated in two ways – directly and using forward obstacle in form of substitute biological material (ballistic gel) to achieve the conditions of firing on-board. Expansion ability of the bullet Action 5 causes a different effect on the target in case of perforation of the substitute material first. The simulation using Finite Element Method system Ansys Autodyn v.14 presents 2D model based on experimental shooting. The simulation introduces the estimation of the substitute material thickness to achieve the ballistic limit for particular parts of the target.
