Finite Element Analysis of 30-mm Cartridge Case

Abstract

During ballistic testing, the 30-mm cartridge case has occasionally coined in the barrel of the M230 gun under unidentifiable conditions. An elastic-plastic stress analysis with increasing ballistic pressure loading up to 70 ksi for the friction and frictionless cases of the 30-mm thin wall steel cartridge case mounted in the M230 gun was performed using the ANSYS finite element computer code. These analyses were carried out to evaluate the response of the cartridge case-barrel-bolt assembly due to the effects of pressure loads. Based on the results obtained, it was found at the maximum applied pressure (70 ksi) no coining developed in the cartridge case-bolt contact zone. Keywords: Finite element analysis, Case-bolt interaction modeling, Stress-strain curve, Case-barrel interaction modeling.
