The test plate-1 was also subjected to impact with bird velocity of 60m/s with the same bird mass. The stress generated due to impact are higher than the allowable stresses of the composite plate. Therefore, the bird completely penetrates through the plate. The impact process at different time intervals is shown in Fig. 7.
