在使用固体连续力学分析表征肺的应力-应变关系时，假设肺实质处于均匀膨胀状态，并考虑从均匀状态的非均匀变形。如果非均匀的变形是小的，非均匀的肺变形问题减少到那些可解的使用无穷小弹性，因为只有小的叠加变形被认为是。利用这种增量方法，测量了肺软组织的相关弹性常数，并通过几个非均匀变形问题的理论分析结果与实验数据的比较，验证了它们的适用性。
In the characterization of stress-strain relationships for the lung using solid continuum-mechanics analysis, the lung parenchyma is assumed to be in a state of uniform expansion and nonhomogeneous deformations are considered from the uniform state. If the nonhomogeneous deformations are small, nonhomogeneous lung deformation problems are reduced to those solvable using infinitesimal elasticity, since only the small superimposed deformations are considered. Using this incremental approach, the relevant elastic constants of lung parechyma have been measured and their applicability has been verified by comparing the results of the theoretical analysis of several nonhomogeneous deformation problems with experimental data.
