提出了胸部系统的两个弹性有限元模型来分析施加载荷的影响。导出软骨的弯曲模型来解释其拉伸模量和压缩模量之间的显着差异。研究的两种结构模型是：1、胸廓（骨架）本身；2、胸廓本体，包括胸廓、肌肉和内部部件。肋骨、软骨、胸骨、椎骨、椎间盘、肌肉以及肺脏和心脏器官均通过各种类型的有限元（即梁、板、膜和实体）进行建模。考虑了 11 种静态载荷和 2 种动态载荷情况，并计算了每种载荷下的应力和位移。对骨骼模型和整个胸部模型进行了比较。
Two elastic finite-element models of the thoracic system are presented to analyze the effect of imposed loads. A flexural model for the cartilage is derived to account for the significant difference between its tension and compression moduli. The 2 structural models studied are: 1st, the thoracic cage (skeleton) by itself, and 2nd, the thoracic body including the cage, the muscles and the internal parts. The ribs, cartilages, sternum, vertebrae, intervertebral discs, muscles, and gross lung and heart organs are modelled by various types of finite elements, i.e. beams, plates, membranes and solids. Eleven static and 2 dynamic loading cases are considered and the stresses and displacements under each loading are calculated. Comparisons are made between the skeletal model and the whole thorax model.
