WebGenerally, a pressure vessel is considered to be "thin-walled" if its radius r is larger than 5 times its wall thickness t ( r > 5 · t ). When a pressure vessel is subjected to a higher external than internal pressure, the above formulas are still valid. However, the stresses would now be negative since the wall is in compression instead of ... WebValves exhibit hysteretic opening and closing behaviors. We modified the model by thickening the vessel wall in order to simulate pumping at higher AAPDs. We use the thick-walled model in the base-AAPD regime for parameter studies involving the transmural pressure (TP), interstitium, vessel wall, and valve leaflets.

WebTo recap, the condition for a thin walled vessel can be written as follows. From there, you can substitute in either a or b for the value of r. Since the entire point of the approximation is that the wall is thin, the model is …
