On the Stability of Lung Parenchymal Lesions with Applications to Early Pneumothorax Diagnosis
Figure 6
Relative force proportion graph. (a) The graph depicts the relative magnitude of the dimensionless forces at play over dimensionless time: pressure , radial stress , internal membrane , fluid structure , and viscoelastic . It is clear that internal pressure and internal membrane forces are the major driving forces behind the oscillations. (b) The three forces that contribute the least (radial stress, viscoelastic, and fluid structure) are plotted on semilogarithmic axes.
