A total of seven human mandibles were struck to breaking point under standardised conditions using a pendulum. The cortical deformation for two impact directions was measured with strain gauge strips located at eight defined sites. Fronto-median impacts led to mostly bilateral and always multiple fractures in the posterior area of the bone, especially in the collum and the condyle. The fracture threshold was between 2.5 and 3.1 kN. Lateral impact caused fractures near the impact area as direct fractures of the ipsilateral corpus. Mainly single and double fractures were observed. For lateral impact the fracture threshold was between 0.6 and 0.8 kN.
总共七个人类下颌骨在标准化条件下使用摆锤撞击至断裂点。使用位于八个特定位置的应变片测量了两个撞击方向的皮质变形。额中撞击导致骨后部区域大多为双侧且总是多处骨折，尤其是在颈部和髁突。骨折阈值在2.5至3.1千牛之间。侧向撞击在撞击区域附近导致骨折，表现为同侧体部的直接骨折。主要观察到单处和两处骨折。对于侧向撞击，骨折阈值在0.6至0.8千牛之间。
