The objective of this research paper is to design the cartridge case and to carry out its analysis by bilinear, kinematic hardening model for water disruptor applications. An attempt has been made in the paper to determine the strain of the cartridge case theoretically and experimentally by conducting tensile testing of test specimen. The maximum strain experienced by the cartridge case is calculated as 0.395 × 10−3 return) using bilinear kinematic hardening model. The aim of this paper is to provide theoretical calculations and technological aspects  about the study of bilinear kinematic hardening model of power cartridge. After the conducting of the trials, it was ensured that smooth extractions of cartridges were observed.
