These findings indicate enhanced levels of target energy absorption and the required energy for bending and tensioning the target. Results indicated that, with increasing initial velocity and ceramic thickness and decreasing support layer thickness, the radius of ceramic cone decreases this ends up increasing residual velocity of the projectile and penetration time and extending the area across which the pressure is distributed. The phenomenon of impact onto ceramic/aluminum composites were modeled using smoothed particle hydrodynamics (SPH) implemented utilizing ABAQUS Software. In order to investigate and evaluate accuracy of the presented analytic model, obtained results were compared against the results of the Florence's analytic model and also against numerical modeling results.
In the present research, a modified model based on radius of ceramic cone was presented for ceramic/aluminum targets. Radius of ceramic cone can largely contribute into final solution of analytic models of penetration into ceramic/metal targets.
