    Simple Cylindrical Pressure Vessels

    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.

    Ship, Tow-Tether and Moonpool Models

    Linked Excel workbooks for preliminary study of the title systems

    The file “Ship, Tow-Tether and Moonpool Models.zip” is a collection of linked macro-enabled Excel workbooks suitable for conceptual to preliminary design of the title systems. The file “Block Diagram.pdf” shows linkages and summarizes each workbooks’ major features. FD and TD at the end of a file name denotes frequency domain and time domain solutions, respectively. Except for the moonpool TD model, which is a solution to the nonlinear equations of motion for the moonpool piston mode, TD solutions are obtained by superposing FD solutions in uniform random phase. ...

    Cable Spool

    A macro enabled Excel workbook for estimating drum loading by a cable.

    Cable Spool.xlsm was developed to estimate loading on a storage drum due to winding of a steel cable. It was later updated to estimate internal loading in GRP ruggedized single fiber fiber-optic cable spools. Adhesive was applied as the cable was wound on a flanged mandrel. After the adhesive cured, the mandrel was removed leaving a spool composed of cable rings bound together by the adhesive. Both cables were very stiff radially. Hence, only axial and bending of the cable and mandrel...

    Planar Elastica

    A collection of technical notes on planar elasticas and sample code

    ...A technical note deriving the governing equations for a planar elastic subjected to general end loading (i.e., combined bending moment, angled direct load and torsional moment). This note is heart of this project. 2. Macro enabled Excel spreadsheet examples that illustrate use of the above result. These examples range in sophistication from large displacement leaf springs to one requiring simultaneous solution of two elastica problems. They are described in the above note. 3. Three supplemental technical notes entitled: a.) Bend Test Models; b.) ...
