Pressure Vessel withpolyethylene core – LoadingProfile• The loading surfaces in the pressure vessel are theinterior surfaces of the vessel and the outer surfaces ofthe polyethylene element.• This is because according to Pascal’s Law, pressure istransmitted uniformly throughout the element whenplaced in a fluid medium.• Hence, the pressure acts uniformly on the surface of thecylindrical element.
Stress Profiles – Surface von Mises and Thermal StressesThe thermal stresses are constant and do not change withtemperature because the temperature difference between theworking fluid and the surrounding temperature is the same underall the pressures taken in the above scenario.
