STRENGTH ANALYSIS OF REINFORCED AND UNREINFORCED BARRELS USED IN SMALL ARMS OF SELECTED CALIBERS. PART III – STRENGTH CALCULATIONS OF REINFORCED BARRELS

The paper describes the leading of two main research tasks. The first one dealt with designs of six barrels for three calibers: 5.56x45 NATO, 7.62x51 NATO, and 12.7x99 NATO. Two barrels were designed for each calibre: one unreinforced and the second one reinforced by a coat. The second task dealt with a computer barrel strength simulation using the method of finite elements to compare the results of numerical and analytical strength calculations and draw the conclusions. Part III includes strength calculations of reinforced barrels for all tested barrels.
