Thin-Wall Pressure Vessel Stress

Hoop and longitudinal stress in a thin-walled cylindrical or spherical pressure vessel. Valid when the wall is thin relative to radius (r/t ≥ 10); the calculator flags it when that assumption is stretched.

σ_hoop r wall thickness t, internal pressure p
Cylindrical vessel shown; hoop stress acts circumferentially, longitudinal stress along the axis.
