Abstract :
The authors have developed an analytical model of lung tissue based on the fundamental properties of the stress-bearing constituents in lung parenchyma. The quasi-static stress-strain curve is found to be a function of elastin stiffness and the distribution of mechanical stops within the collagen fiber matrix. From measured stress-strain curves, the stop-length distributions follow an inverse power law which is indicative of the fractal nature of lung tissue structure
