Excel workbooks suitable for preliminary design and analysis
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...
A Fortran code for design and analysis of ring-stiffened shells
DAPS4e is an updated version of a Fortran code by John Renzi for design and analysis of monocoque and ring-stiffened circular cylindrical shells [DOI: 10.13140/RG.2.2.18176.92165]. The following failure modes are considered:
• Shell stresses and displacements at mid-bay and ring-frames.
• Ring-frame stress.
• Axisymmetric collapse (AC).
• Elastic and Inelastic Interbay Buckling. (EIB and IIB).
• Elastic and Inelastic Monocoque Instability (EMI and IMI).
• Elastic and Inelastic...
