Low-Velocity Impact on GLARE 5 Fiber-Metal Laminates: Influences of Specimen Thickness and Impactor Mass

Impact response and damage induced by a drop-weight instrument on glass reinforced (GLARE) 5 fiber-metal laminates of different thicknesses were studied. The effect of the impactor mass was also considered. The damage characteristics were evaluated using both the nondestructive ultrasonic and mechanical-sectioning techniques. Only the contour of the entire damage area can be obtained using ultrasonic C-scan; whereas, more details of the damage...
