Abstract:

Ballistic impact experiments were performed on ceramic laminate targets at three scale sizes, nominally 13, 16, and 112, to quantify the effects of scale on various responses, in particular, the ballistics limit velocity. The experiments were carefully designed and controlled so that the different scale sizes were high fidelity replicas of each other. A variety of responses, such as residual projectile quantities, hole size, and the extent of bulging, were measured. Some of the measured quantities showed little or no dependence on scale size, whereas other quantities, particularly the ballistic limit velocity, were found to vary with scale size. The percentage difference was quantified, and the results extrapolated to estimate full scale response from the subscale tests.
