Pressure tests were performed on certain well-defined points in the median-sagittal plane of soft part covered skulls of 40 human corpses. It was found that the elastic behaviour of the skull obeys Hooke's law, thus the modulus of elasticity is the Ist differential quotient in the stress-strain diagram. Beside the vectorial nature of the compression force the point of application is also of decisive importance. The globe-ellipsoid theories do not correspond to the structure of human skulls. Autopsy revealed over 50% more confirmed fractures than the X-ray pictures. This contradiction in the diagnosis of fractures on the human skull can be reduced by series of X-ray pictures. The lines of the fractures run to the most part along the Benninghoff--Goerttler pillars of strength. Additional biostatic parameters (maximum load before breaking, coefficient of elasticity, stress, elongation etc.) were also obtained which permit an insight into the specific mechanic structure of the human skull and its load-bearing ability.
对40具人类尸体覆盖软组织的颅骨矢状正中平面上的某些明确部位进行了压力测试。结果发现，颅骨的弹性行为符合胡克定律，因此弹性模量是应力-应变图中的一阶微商。除了压缩力的矢量性质外，施力点也至关重要。球-椭球体理论与人类颅骨结构不相符。尸检显示，确诊骨折比X光片多50%以上。通过一系列X光片可以减少人类颅骨骨折诊断中的这种矛盾。骨折线大多沿着本宁霍夫-格特勒强度支柱延伸。还获得了其他生物力学参数（断裂前的最大负荷、弹性系数、应力、伸长率等），这些参数有助于深入了解人类颅骨的具体力学结构及其承载能力。
