Improved Florence model and optimization of two-component armor against single impact or two impacts

A new version of the Florence model taking into account the ballistic resistance of the ceramic plate in a two-component armor is suggested, verified and used for armor optimization. The direct problems (maximization of the ballistic limit velocity for a given areal density (AD) or a total thickness (TT) of the armor) and the inverse problems (minimizations of AD or TT for a given impact velocity) are investigated in the case of a single impact. We also formulated and studied the armor optimization problems with a repeated impact. Numerical results are presented for aluminum/alumina armor.
