Abstract

In this paper, the possibility of plastic deformation of rifle and gun barrels is studied through the numerical methods. When a rifle or tank gun is fired, the expansive deformation of the barrel can occur by the explosive pressure and the thermal effect. Using the ABAQUS program, the stresses and displacements are computed for the elastic and elastic-plastic material property, and the possibility of plasticity deformation is investigated. In conclusion, rifle and tank gun barrel the plastic deformation occurred in some parts of the barrel
