BALLISTIC PERFORMANCE OF ADHESIVELY BONDED JOINTS
Abstract
In this study, ballistic performance of adhesively-bonded Single Lap Joints is investigated experimentally and numerically. Using a specially-designed experimental set-up, a projectile with mass of 1.25 gr and density of 11.3 gr/cm3 was fired to the joints at a velocity of 288 m/s. The joints with a thickness of 4 mm and two different overlap lengths, 15 mm and 25 mm, were first subjected to the ballistic and then to the quasi-static tensile tests. When the impacted joints were compared to the non-impacted ones, it was found that while the joints with the 15 mm overlap length mechanically deteriorated, those with the 25 mm length were not affected. These results were validated numerically via the ABAQUS package program. Johnson Cook behaviors of the materials were used as input data in the analysis.
