Comparative Stress Analysis of an Artillery Projectile Body

Abstract

This paper presents comparative stress analysis of an artillery projectile body using FEM and classical theoretical method. The aim of this analysis is to show that results of stresses in characteristic cross sections obtained by the classical theoretical method and stresses obtained by FEM calculation gives good agreement. The projectile 105 HE M1 was used as an example for the comparative stress analysis. Based on the results and their good match, it can be concluded that the numerical FEM analysis can be reliably used for strength analysis of various types of artillery projectile bodies.
