This Walled Pressure Vessels – Hot Dogs!

 Model Description This is a simple demonstration of the basic principals underlying the behavior of thin-walled pressure vessels (TWPVs).  A hot dog is used to show that hoop stresses are twice as high as longitudinal stresses in cylindrical pressure vessels and failure occurs along the length of the hot dog.  The failure that occurs in […]

 Overview This is a simple demonstration of the basic principals underlying the behavior of thin-walled pressure vessels (TWPVs).  A balloon or balloons are used to show that hoop stresses are twice as high as longitudinal stresses in cylindrical pressure vessels. Principle The basic derivation for TWPV behavior states that for a cylindrical pressure vessel   […]
