Simple Cylindrical Pressure Vessels

SCPV is a family of three macro enabled Excel workbooks for analysis of long cylindrical pressure vessels with flat endcaps subjected to external hydrostatic pressure.

CPVanalysis.xlsm does stress and stability analyses. It plots stresses, deflections and the equilibrium path for imperfect circular cylinders showing the onset of yielding and limit points in relation to elastic and inelastic bifurcation buckling pressures. Two types of initial geometric imperfections, outer diameter out-of-roundness and outer-to-inner diameter eccentricity with a phase angle between them, can be considered.

CPVparametric.xlsm, does parametric analyses. It plots performance parameters against depth or pressure for up to five different combinations of materials and shell geometries including initial imperfections.

CPVcreep.xlsm does analysis of creep instability in vessels with initial mode-2 out-of-roundness imperfections.

Supporting documentation is included.
