Experimental drop weight impact tests have been performed to examine the failure characteristics of small-scale clamped rectangular plates stuck laterally by a mass with a spherical indenter. The experiments are conducted on aluminium and steel plates of the same bending stiffness. Thus, the impact tests describe the behaviour of strength-equivalent ship building materials subjected to rapidly varying loads. The experimental results are presented in terms of the force-displacement responses and the failure modes of the specimen plates, which are very sensitive to the diameter of the indenters. Also, the experimental results show that the critical deflection is similar for both the aluminium and steel plates while some differences are observed in the critical force and energy. In addition, the magnitudes of the critical deflection, force and energy are compared a static theoretical prediction to allow the selection of equivalent impact strength plates.
