LOW VELOCITY IMPACT OF PLATE AND HEMISPHERIC IMPACTOR: PHYSICAL EXPERIMENT, NUMERICAL COMPUTATION, AND APPLICATION TO REAL SYSTEM
Preview AbstractSteel plates subjected to low velocity impact were numerically analyzed, and physically tested. The impactor has hemispheric tip nose, and the square plate has four fixed edges. Mindlin plate theory and Hertz contact law were used for the formulation of the impact problem, and some numerical treatments for the reduced integration, Newmark time integration scheme, associative flow rule, and plastic hardening were appropriately applied. A simple and efficient analysis program for plate impact was generated, and the results were compared with those of physical impact experiments. A drop test system was installed, and the impact behavior was measured with sensors. The comparison showed reasonable results, and the main parameters of plate impact were also analyzed.
