“…Experimental studies [13,21,[27][28][29][30] confirm the negative effect of ammunition storage time on muzzle velocity. The authors of this study obtained the dependence of the change in the relative value of the initial velocity of the projectile on the storage life of ammunition at 10 ≤ τ ≤ 50 years, in the form of a second-degree polynomial [4]:…”

Despite the fact that a large amount of small arms ammunition has been used up over the past two years, their stocks in warehouses and arsenals in various countries are quite large. And their shelf life is 20 years or more. In addition, over time, the number of such ammunition will increase. Among the large number of requirements for modern small arms, one can highlight the provision of the necessary survivability of its parts and mechanisms. The problem of barrel survivability is especially important. One of the factors affecting barrel survivability is changes in internal ballistics parameters. In turn, these parameters change when using ammunition whose service life exceeds the warranty. In this regard, the task of studying the survivability indicators of small arms barrels when using post-warranty ammunition seems relevant. The requirements for barrel systems and factors affecting the wear of the barrel bore of powder charges during long-term storage have been determined. An analysis of changes in the ballistic characteristics of powder charges was carried out, which allows to state increased wear of barrels when using ammunition with long storage periods. The dependencies for determining the limit number of shots from a weapon sample are analyzed. A method for predicting barrel survivability when using long-term storage ammunition is proposed. Data are presented on an experimental study to determine changes in barrel survivability as a result of the use of long-term storage ammunition by estimating changes in the initial velocity of the projectile. Based on the results obtained, ways for further research are proposed in the direction of expanding the range of ammunition and weapons

“…[6][7][8][9][10][11][12][13][14] For example, acquiring the transient surface temperature of a linear electromagnetic propulsion slide rail or gun barrel is difficult because the temperature increases abruptly in several hundred microseconds due to high-speed sliding. [15][16][17][18][19] Therefore, the time resolution of the transient surface temperature measurement needs to reach at least the microsecond level, and even the nanosecond level to reveal the phase explosion of the high-speed friction erosion process.…”

“…First, Lame's equation was applied by the authors in some works to calculate the endurance of tubes subjected to internal pressure only [5,6]. Later, this method was extended to the case of unevenly heated cylinders [7][8][9]. The work [7] presented a method for calculating the stress of a gun barrel under the combined thermo-mechanical load, namely the contact and friction loads of the bullet and the heat and pressure of the powder gas.…”

“…The finite element models were established using Abaqus software for the increase of the temperature and stress of the inner bore wall beared to cyclic loads. Results shown that the stress exceeded the yield strength of 30SiMn2MoVA gun barrel steel [8]. In the other work, the thermo-mechanical combination theory was handled for the 3-D transient heat transfer and stress analysis.…”

The problem of determining the stress state of the rifled-bore barrel when firing was presented in this article. Where the effects of rifling parameters such as the quantity of grooves n, groove width a, depth of groove t, radius of groove corner ρ were investigated. A rifled-bore barrel has been modeled and investigated by using Ansys software on the basis of finite element method. The problem has only been treated under pressure load in static case. The article can be used for reference to improve the accuracy in calculating design and manufacturing gun barrel.
