Experimental and Numerical Structural Analysis of 155mm Artillery Shell

Abstract

The current research work encompasses experimental , numerical and analytical studies for structural analysis of 155mm artillery Shell ERFB BT. The research aims : (i) to identify the quasistatic tensile properties at room temperature and the elevated temperatures, (ii) to investigate the dynamic tensile properties of the projectile 155mm ERFB BT material at medium strain rates, (iii) to study the effect of abrupt change in geometry of the components of the projectile on structural failure by performing notch tensile tests followed by the fractographic examination , (iv) to carry out stress analysis of the projectile subjected to maximum chamber pressure by analytical method, and (v) to check plastic deformation of the projectile body by undertaking a 3-D explicit dynamic structural analysis of 155mm HE ERFB BT during gun launch conditions by finite element method using FE code ABAQUS/Explicit newline
