Development of impact model for ceramic-faced semi-infinite armour

A model is presented which predicts the penetration of projectiles into ceramic faced semi-infinite armour. This model facilitates the study of material property and armour configuration changes on penetration. The model results correlate well with previously published experimental data for long-rod penetrator impacts with similar armours. Tests with spherical projectiles against ceramic faced semi-infinite armour were carried out, for which the model results correlated reasonably well.
