Alveolar Edema

This study has been designed to investigate the concept that the passage of red blood cells (clearly seen “bulging” into the air space in all scanning electron micrographs of the alveolar surface) can produce a net force tending to return any excess fluid to the interstitium. Measurements of surface tension over the time frame and probable surface area excursion incurred by a passing red blood cell show an appreciably higher value corresponding to the expanding surface, which is convex with respect to air, than when it is compressing and concave. The mean difference in surface tension of about 16 dyn/cm (mN/m) translates into a net driving force of approximately 6 mmHg induced by this rapidly alternating microcurvature reflecting the highly dynamic state of the living alveolar wall. The significance of the microcurvature of the alveolar surface is emphasized in relation to surfactant function.

Large Deflection Theory

The buckling of a round tube or curved A plate under axial compression is an example of that class of instability in which the initial buckled form becomes itself at once unstable. As a result the buckle immediately develops to a large amplitude, often with loud noise. This class of instability has been aptly termed “oil canning” from a familiar example.Thorough investigation of oil canning problems must always be tedious. As for any buckling problem it is essential to use large deflection theory and, since the amplitude of buckle rapidly becomes large, it is necessary also to consider in detail the distribution of the membrane (or mid-plane) stresses due to the buckle. This necessity, in combination with peculiar buckled forms, renders the complete solution even for a tube extremely difficult and tedious. Moreover, since the buckled form for a complete tube does not accord at all well with the edge conditions for a curved plate, the full analysis for the latter is almost prohibitively difficult.
