The Stress (Tangential) out Cylinder calculator computes the tangential stress on the outer wall of a closed cylindrical vessel.
INSTRUCTIONS: Choose units and enter the following:
Stress (Tangential) out Cylinder (σext): The results are returned in units of Newtons per meter squared.. However, these can be automatically converted to compatible units via the pull-down menu.
This equation for stress computes the tangential stress (`sigma_t`) on the outer wall of a closed cylindrical pressure vessel.1 The tangential stress is also sometimes called the "hoop stress" as it is the surface wall stress all the way around the circumference of the cylinder. The pressure inside the vessel for this equation is assumed to Pi = 0.
The Tangential Stress outside a Cylinder calculator computes the tangential stress on the inner wall of a closed cylindrical pressure vessel.1 The tangential stress is also sometimes called the "hoop stress" as it is the surface wall stress all the way around the cylinder. The formula for the Tangential Stress in a Cylinder is:
`sigma_"t_ext" = -P*(r_o^2 + r_i^2) / (r_o^2 - r_i^2)`
