S-S Curve.zip includes: 1. A macro enabled Excel workbook (S-S Curve Helper.xlsm) for creating a Stress-Strain curve using the Ramberg-Osgood formula and commonly available material properties. Combinations of tensile or compressive and engineering or true forms can be selected. 2. A procedure for Stress-Strain curve scaling. 3. A formula for plastic Poison’s Ratio between the proportional limit and fully plastic condition.

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...

DAPS4e is an updated version of a Fortran code by John Renzi for design and analysis of monocoque and ring-stiffened circular cylindrical shells. 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 General Instability (EGI and IGI). • Ring...

... core. d. Three-layer sandwich-wall with isotropic outer layers and orthotropic core. Stress-strain solutions for all constructions are based on thick-wall three-dimensional elastic theory. Elastic Monocoque Instability pressure is calculated. Instructions on using each worksheet are given therein. 2. Technical notes outlining the underlying theory and discussing the above four types of PVs.

Coexlam is a VBA Excel application that performs composite laminate analysis. Laminate theory is used with several strength criteria: maximal stress, maximal strain, Tsaï-Hill and Tasï-Wu. A help including a Getting Started part is now available in the application. The users can add their own formulas or application, an example is provided with a tank under pressure. Several load cases can be calculated in one time in the Print sheet. Laminates can be saved in the Library sheet. Several...
