Abstract
The study concerns the transverse deformation behavior of a penetrator surrounded by sabot in a deformed gun barrel. In the gun barrel, transverse deformation occurs in the penetrator due to problems such as deflection by gravity, or geometric tolerance caused by the manufacturing process. This deformation causes structural instability problems and affects out-of-gun barrel movement. In addition, the deformation and structural safety of the penetrator is affected by the sabot supporting the penetrator. The finite element method was used to evaluate the effect of the sabot. Deformation and stress analysis were performed for the penetrator moving in the gun barrel, and the effect of the elastic modulus of the sabot on the deformation of the penetrator was studied.
