thin-walled vessel (sphere) pressure load calculator

enter the value and click "calculate", the calculation result will be displayed.

`δ_[sph]=[p×r]/[2×t]`      `R=[p×r^2(1-v)]/[2×E×t]`
`V=[2×p×π×r^4(1-v)]/[E×t]`
δsph = stress p = uniform internal pressure
r = radius t = thickness v = poisson’s ratio
e = modulus of elasticity r = increase in radius
v = volume increase

thin-walled vessel (sphere) pressure load calculator pressure vessels are held together against air pressure due to the tension within the walls of the vessel. the stresses in a spherical-shaped shallow-walled pressure vessel are related to the internal gauge pressure, the inner radius of the sphere, the wall thickness, and the density of the material. a container may be considered "shallow walled" if the diameter is at least 10 times (sometimes called 20 times) greater than the wall depth.
