Empty Pressure Vessel – Pressure vs. Stress plot• In the case of empty pressure vessel, the plot between the internallyapplied pressure and the maximum von Mises stress has been found to beessentially a linear plot. This is in accordance with the theoretical findingsof the plot in case of a cylinder under loading.• The linear increase is attributed to the fact that the amount of expansiveforce on the surface has been increased leading to an increase in theprincipal stresses in the walls and consequently, in the magnitude of the vonMises stress.• The linear increase results from the fact that within elastic range, therelation between pressure applied or stress applied results in a linearvariation of the strain produced in the vessel, in accordance to the Young’srelationship between stress and strain.
