Dynamic penetration of a RGID flat striker into an inhomogeneous target along the normal and at an angle

The problem of dynamic penetration of a rigid flat striker into an inhomogeneous target along the normal and at an angle is considered. The article presents a mathematical model, differential equations and corresponding Cauchy problems. The algorithm for the numerical solution of the problem is implemented in the Turbo Pascal language in the object-oriented environment of the Borland Delphi 7 compiler using graphical tools and high-precision numerical methods necessary for visualizing the results. Verification of the model is based on an analytical solution for the problem of normal penetration. Based on numerical experiments, rational characteristics of a two-layer target of minimum weight are obtained.
