Abstract

The present study is concerned with the estimation of power in Karate-doh. The measuring method and numerical estimation for impact forces produced by Karate-doh hand techniques such as Syutoh-uchi, Tettsui-uchi and so on, are discussed by experiments (by means of Tameshi-wari) and numerical simulations. In the beginning, an impact experiment of simply supported concrete beams was conducted to examine the impact response and the impact breaking of the concrete beam. And then Tameshi-wari of simply supported concrete beams was performed. In order to understand the mechanism of impact breaking of concrete beams by Karate-doh hand techniques, a numerical simulation was also carried using a dynamic finite element method with a Newmark-β method. The impact force generated between the hand and the concrete beam was estimated to be beyond 4.5 kN. It was also found that a reaction at both ends of the beam was almost never generated by virtue of the dominant modes of bending deformation of the beam. This indicates that, by means of Tameshi-wari, the impact breaking of the concrete beam floating in air is quite within the bounds of possibility. Therefore Tameshi-wari for concrete beams suspended in air was also tried and achieved the predicted results.
