TY - JOUR T1 - DETERMINATION OF THE CRITICAL POINT ON SNIPER BARREL IN TERMS OF THE STRESS AND DEFORMATION CONCEPTS AU - Doğru, Mehmet Hanifi PY - 2019 DA - December Y2 - 2019 JF - The International Journal of Materials and Engineering Technology JO - TIJMET PB - Necip Fazıl YILMAZ WT - DergiPark SN - 2667-4033 SP - 60 EP - 63 VL - 2 IS - 2 LA - en AB - AbstractThe impact performance of the material is criticalproperty in the weapon industry. In particular, the pressure distribution conceptin barrel has revealed the need to work on this issue. Therefore, the behaviorof the barrel was investigated, when the explosion pressure was realized in thebarrel. In this study, different pressure values were applied to the inside ofthe barrel to obtain a critical stress region. The barrel of the new generationlong-range sniper weapon of the American Barret company, which is legendarywith the M82A series, was used. 3D barrel model was created in SOLIDWORKSprogram. ANSYS workbench static structural toolbox wasused to perform the proposed study. Within this study, the critical points insniper weapon barrel were determined in terms of the stress and deformationconcepts.
