Abstract

In the present investigation, failure assessment diagram (FAD) using R6 approach has been established for structural integrity analysis of a battle tank gun barrel. FEM based modelling was carried out to evaluate maximum stresses in the barrel section during firing. A detailed sensitivity analysis of various geometres, service and material parameters has been performed to assess their criticality on overall safety of the structures. The study has been carried out using actual material and firing data of a battle tank gun barrel and therefore it can give useful insight to a designer while selecting a material and designing a similar component.
