A finite element model is formulated for determining the macroscopic stress, strain and deformation of the lung parenchyma. The effects of nonlinear elastic behavior, finite deformation, and interfacial tension are included. An incremental approach is used. Illustrative results for deformation of the lung due to its weight are included. The necessity of including surface tension explicitly is demonstrated.
建立了一个有限元模型，用于确定肺实质的宏观应力、应变和变形。该模型考虑了非线性弹性行为、有限变形和界面张力的影响。采用增量法。给出了由于肺自身重量导致的变形的示例结果。证明了明确包含表面张力的必要性。
