The fragmentation of dynamically loaded homogeneous brittle plates was studied by means of a drop test facility. Multiple tests were conducted on five different size model plaster plates under two loading conditions. The results indicated that the plate response is statistical in nature and that a definite fracture pattern emerges. Furthermore, they give rise to the working hypothesis that the cracks propagate along the maximum stress trajectories associated with the forced vibration mode. Author
