This fact leads to interesting stability properties when two balloons of different radii are interconnected, see [1, 2, 3]. Here, however, we investigate what happens when a single balloon is inflated, say, by mouth. We simulate that process and show how the maximum of the pressure-radius characteristic is overcome by the pressure in the lungs and how the downward sloping part of the characteristic is ‘bridged’ while the lung pressure relaxes.en510 Mathematik620 Ingenieurwissenschaften und zugeordnete Tätigkeitenrubber balloonsMooney-Rivlin materialnon-convexitystabilityArticle1741-3028
