Numerical simulations with ANSYS/DYNAMIC EXPLICIT have been performed to study the Ballistic perforation of 12 mm thick Weldox 460E steel plate struck by projectiles with different cone angles (30°, 60°, 90°, 120°, 180°) under normal impact. The Johnson-Cook plasticity model combined with the Johnson-Cook dynamic failure model have been used to analyze the perforation of the target plate and the failure modes. The objective of the work was to calculate the ballistic limit, residual velocity and absorbed energy during the perforation process. Various failure modes as well as perforation process are obtained for different cone angles. Results of numerical simulation are validated with experimental results as available in literature.
