  We are involved in the structural design and structural evaluations of the safety and functionality of rapid transportation such as vehicles and aircraft. The crash safety of vehicles and damage detection of aircraft etc are both representative examples of this theme. In particular we are carrying out research using the keyword of “Impact phenomenon” and researching the impact resistance of new materials such as carbon fiber reinforced composite materials and shock absorbers that put a folding structure to practical use. We frequently carry out inspections using CAE (a type of computer simulation) in addition to various intensity experiments in our research, and develop test productions. Recently we have also been emphasizing damage diagnosis of architectural constructions and developing a system that can be used to evaluate the generation status of cracks in real time. We have a lot of themes of research that are being promoted in cooperation with car and aircraft manufactures etc.
