| ABSTRACT Design of the high explosive (HE) warheads is confronted with series of contradictory requirements. Modeling of fragment size, mass distribution is one of the great importance for determination of fragmenting warhead efficiency. In this work a numerical solution for Mott’s formula was built using MATLAB for determination of mass distribution and average mass of fragments. A 105 mm high explosive HE projectile was tested in a pit test and the results are comparing with numerical results. The comparison show small error in average mass of fragments (0.03%). A combination of this method with Held’s formula leads to calculate the warhead characteristics λ and B. This gives a good approach of calculating different fragmentation parameters for different warheads | ||||
