The actions of several human respiratory muscles have been inferred from finite element analysis of the rib cage. The human model is based on anatomic and mechanical measurements in dogs and human cadavers. As in an earlier canine model, the external and internal (interosseous) intercostal muscles were found to cause, respectively, inspiratory and expiratory displacements of the rib cage, in agreement with the two-dimensional geometric analysis of Hamberger. When extended to three dimensions, Hamberger's analysis helps explain why muscles at the side of the rib cage produce changes in the anteroposterior diameter, whereas muscles at the front and back of the rib cage cause changes in the transverse diameter.
通过对胸廓的有限元分析推断出了几种人体呼吸肌的作用。该人体模型基于对狗和人体尸体的解剖学和力学测量。与早期的犬类模型一样，发现肋间外肌和肋间内（骨间）肌分别导致胸廓的吸气和呼气位移，这与汉伯格的二维几何分析结果一致。当扩展到三维时，汉伯格的分析有助于解释为什么胸廓侧面的肌肉会导致前后径的变化，而胸廓前后的肌肉会导致横径的变化。
