The radial, hoop, and axial stresses are the principal stresses in this system.har_rai said:Homework Statement
Hi, I trying to calculate principle stresses for pressure vessel (thick walled) which is pressurized from inside. I calculated all 3 stresses radial, hoop and axial and looking for what formulae to use to get to principle stresses.
thanks

The Attempt at a Solution
Thanks for the reply. So there is no shear stress in this, only 3 normal stresses (radial, hoop and axial).Chestermiller said:The radial, hoop, and axial stresses are the principal stresses in this system.

A thick walled pressure vessel is a type of container used to hold fluids or gases under high pressure. It is typically made of metal and has a thick wall to withstand the internal pressure without deforming or bursting.
The purpose of a thick walled pressure vessel is to store and transport fluids or gases at high pressure. It can also be used in various industrial processes such as chemical reactions, heat exchange, and storage of compressed gases.
The principle stresses in a thick walled pressure vessel are the axial stress, hoop stress, and radial stress. These stresses are caused by the internal pressure and the geometry of the vessel.
The principle stresses in a thick walled pressure vessel can be calculated using the Lamé equations, which take into account the vessel's geometry, material properties, and internal pressure. These equations can be solved using various analytical or numerical methods.
The principle stresses in a thick walled pressure vessel are affected by factors such as the vessel's dimensions, material properties, and internal pressure. Other factors that can influence the stresses include temperature, corrosion, and external loads.
