Abstract: Advanced mean value method is an efficient method in reliability analysis under the condition ?i implicit limited state functions. Combined with the finite element method, the reliability of armor pierc?ing fin stabilized discarding sabot projectiles having large slenderness ratio was calculated. Randomness of the bore pressure, the mechanical property of materials, and the tolerances between the sabot and core are all taken into consideration, so that appropriate results are obtained. Furthermore, the suggestions on im?provements in its strength and reliability are proposed.
