TLDR
The temperature dependence of small degassed hamster lung strip mechanics was examined to develop insights into the molecular basis of lung elasticity, suggesting that strips behave like rubber polymers near physiological temperature.Abstract:

TL;DR: Although there were some quantitative differences between predictions and experimental observations, the dynamic behavior of lung parenchyma was generally consistent with that of a network in which load is transferred from one fiber to the next by the agency of friction acting at slipping interface surfaces.
Journal ArticleDOI
Material model of lung parenchyma based on living precision-cut lung slice testing.
TL;DR: A novel constitutive model of lung parenchyma is described, which can be used for continuum mechanics based predictive simulations and will help to model the behavior of the pulmonary parenchema and to quantify the strains and stresses during ventilation.

Mechanical behavior of excised canine visceral pleura
TL;DR: The visceral pleura was found to behave similarly to other biological soft tissues and required preconditioning to yield repeatable responses and appeared to possess in- plane transverse isotropic material symmetry and to exhibit strong in-plane mechanical coupling at lower loads.
Journal ArticleDOI
A micromechanical model of lung tissue rheology.
TL;DR: It is shown that the behavior of this model closely approximates quasilinear viscoelasticity, in which the static stress–strain behavior is separable from the dynamic stress relaxation behavior.
