Thin-Walled Pressure Vessel Hoop Stress Calculator

σ_hoop = P·r/t — circumferential stress in a cylinder.

Calculates hoop (circumferential) stress σ_h = P·r/t and longitudinal stress σ_l = P·r/(2t) in a thin-walled pressure vessel (cylinder), where P is internal pressure, r is radius, t is wall thickness.
