SZMELTER, J. and LEE, C.K., 2007. Prediction of fragment distribution and trajectories of expolding shells. Journal of Battlefield Technology, 10 (3), pp. 1-7
A semi-empirical model allowing for prediction of natural fragmentation of exploding shells is described. The
initial velocity, projection angle, size and location, obtained for each fragment, are used by a point mass trajectory
routine to determine the overall fragment distribution on the ground and to model fragments hitting a threedimensional
object. Examples of validation against experimental data for 105mm shell and a mortar bomb are shown.
The proposed model is useful for munition assessments, including a prediction of safety hazard in a credible accident.
