CHE – 809 Ballistics
Campus SCME
Programs PG
Session Fall Semester 2016
Course Title Ballistics
Course Code CHE – 809
Credit Hours 3-0
Course Objectives To impart the important characteristics of materials and to show how the microsctructure determines properties and is a function of structure. To analyse the defeat of armour systems by projectiles (external ballistics) and to determine appropriate materials to incorporate into armours and projectiles.
Detail Content Armour Materials & Structures; Failure modes, deformation mechanisms, high strain rate effects. Optimisation of properties to resist penetration, plugging and scabbing, The relation between mechnical properties and armour performance, Metallurgical characteristics of steel, aluminiumarmours& ceramic armour. Armour structures – application of lamination, spacing, obliquity and reactivity. External Ballistics: Shaped charge performance & target effects; Explosively formed fragments, Optimisation of kinetic energy penetrator materials. Armour Calculations and Predictions. An introduction to the mechanisms of armour penetration; Low and high KE density, HEAT and HESH, Definition of Ballistic limit, Penetration & Performance, Predictive formulae for low KE density attack, Milne de Marre Formulae, Equivalent Protection factors. Whittaker’s directional Probability Variations; The distribution of tank armour, the relationship between mobility, protection, threat level and survivability, Computer modeling. Hydrodynamic Attack; Heat and Long Rods, Simple & Modified Hydrodynamic Theory, Effects for velocity, length to diameter ratio, density, hardness etc. on performance of long rods. Stress Wave Effects; The HESH round, Design of Composite Armour. Computer simulation of high velocity impact.
