Sternal injury, gross cardiac pathology, and cardiac dysrhythmias following nonpenetrating impact by a variety of impactors to the sternum of experimental animals are described. The biomechanical response of the chest wall to the impact and the associated transient pressure changes within the heart are presented, and a correlation between injury severity and chest wall displacement is demonstrated. A simple model is then developed to predict chest wall displacement if the mass, velocity, and dimensions of an impactor are known. The model demonstrates the dependence of chest-wall displacement upon preimpact kinetic energy, impact diameter, and target size.
描述了实验动物胸骨受到各种撞击器非穿透性撞击后的胸骨损伤、心脏大体病理学和心律失常情况。介绍了胸壁对撞击的生物力学反应以及心脏内相关的瞬时压力变化，并证明了损伤严重程度与胸壁位移之间的相关性。然后开发了一个简单模型，用于在已知撞击器的质量、速度和尺寸时预测胸壁位移。该模型展示了胸壁位移对撞击前动能、撞击直径和目标大小的依赖性。
