| Outline of Final Research Achievements |
Ceiling impact has been measured using various materials from one to twenty m high with a dummy head to propose the safety criteria of ceilings. On this research, the numerical analysis simulating the ceiling drop tests was done, and the impact load estimation method for new ceiling materials was developed.
On this research, it is confirmed that the results obtained by the impact analysis are strongly correlated with the experimental results. Also, the strain rate dependency is considered by the quasi-static tests and the SHPB method, and the required material values for the numerical analysis were accumulated.
