WebFigure 8-37 shows a cross section of a thin cylindrical pressure vessel reinforced with stringers. The axial stress in the shell is. Fmmer = pr 2t (bt + 2μAst bt + Ast) (8-22) and that in the stringer is. Fstmer = pr 2t (bt(1 − 2μ) bt + Ast) (8-23) The circumferential stress is the same as that in a simple thin cylinder. Fmt = pr t. WebThe classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is: σ θ = P · D m / ( 2 · t ) for the Hoop Stress Thin Wall Pressure Vessel Hoop Stress Calculator. Where: P = is the internal pressure t = is the wall thickness r = is the inside radius of the cylinder. Dm = Mean Diameter ...
