Abstract
The impact performance of the material is critical
property in the weapon industry. In particular, the pressure distribution concept
in barrel has revealed the need to work on this issue. Therefore, the behavior
of the barrel was investigated, when the explosion pressure was realized in the
barrel. In this study, different pressure values were applied to the inside of
the barrel to obtain a critical stress region. The barrel of the new generation
long-range sniper weapon of the American Barret company, which is legendary
with the M82A series, was used. 3D barrel model was created in SOLIDWORKS
program. ANSYS workbench static structural toolbox was
used to perform the proposed study. Within this study, the critical points in
sniper weapon barrel were determined in terms of the stress and deformation
concepts.
