頭がい骨を円筒形容器として中にほとんど非圧縮の柔らかい弾性体を詰めた頭がい模型を用いて, 有限要素法により頭がい衝撃問題の基礎的研究を行った. 脳はせん断弾性係数が体積弾性係数にくらべて非常に小さく従ってポアソン比が0. 5に近い材料なので, 普通の変位法では誤った結果を与える. この困難を克服するため Herrmann の変分原理を用いた. 内部弾性体の圧力応答に対してその体積弾性率と端板の変形の影響が大きいことを明らかにした.

In August to September of 1995 the authors conducted an anthropometry of the head and face and measurement of the dental arch on Chinese Liao-Ning (66 males and 83 females), and the results were discussed. Furthermore, the correlations between the measurements of head and face, and those of dental arches and palate height were studied. The main results obtained are as follows : 1) Head length : the mean value for the male is 181.0mm and for the female 170.4mm. Both belong to Middle type. 2) Head breadth : the mean value for the male is 155.3mm and for the female 151.6mm. Male belong to Middle type and females belong to Wide type. 3) Bizygomatic breadth : the mean value for the male is 140.3mm and for the female 133.5mm. Both belong to Middle type. 4) Morphological face height : the mean value for the male is 124.0mm and for the female 114.6mm. Both belong to High type. 5) The head-type of the Chinese Liao-Ning belongs to Hyperbrachycephalic type and the face-type to Leptoprosopic type. 6) Correlation : The significant positive correlation is noted between the morphological face height and lower dental arch length only in the male, while that between morphological face height and palate heght is noted in both male and female.
