Abstract: To develop a more widely applicable and accurate formula for calculating fragment scattering angles, this study combines experimental and numerical simulation results to construct an artificial neural network (ANN) prediction model for the spatial distribution parameters of fragment scattering angles. Subsequently, a calculation formula for the spatial distribution parameters and the distribution of the fragment scattering angle along the casing axis is established. The results indicate that for typical cased charges, the fragment scattering angle ranges from −20°~15°, and its absolute value exhibits a trend of initially decreasing and then increasing from the detonation end to the non- detonation end. The fragment scattering angle increases with the mass ratio and decreases with the increase in end cap thickness ratio. The proportion of fragments scattering downward increases with the decrease of aspect ratios. The ANN model effectively predicts the spatial distribution parameters of fragment scattering angles, and the established calculation formula for fragment scattering angles has good applicability and accuracy.
