Research on target damage efficiency calculation algorithm based on finite element analysis method

To study the target damage efficiency of the projectile fragment for the target, a penetration kinetic energy calculation algorithm is put forward to analyze the target damage probability based on projectile spatial coordinate. According to the target features, the finite element analysis method was used to establish the mathematical model of the damage vulnerable area and calculate the kinetic energy of target damage effectiveness evaluation. The ratio of the difference between effective fragments penetration kinetic energy and maximum dynamic deformation work of the target material is utilized to calculate the target damage probability. The target damage level standard was described to evaluate the target damage efficiency. The simulation software ANSYS is adopted to realize the penetration simulation and give out the curves of variational velocity and variational energy on the process.
