Hole effect on Plate Shear BucklingThere are limited options for dealing with a hole in a shear web. There is a often used ESDU reference for this situation. ESDU sheets are a commercial product and unless you, or your organization have paid for them, you should not use them.

There is a NASA reference that gives the same shear buckling reduction factors as the ESDU sheet (NASA-CR-132548) and also gives the experimental basis for the reduction and correlation with analysis. As with the ESDU methods the method is limited to a square shear panel with a central circular hole that has no reinforcement. We also have extrapolated the curve down to a larger d/b ratio:

Shear Buckling with hole

Further reading on this subject does indicate that this approach is appropriate or conservative for a central, circular hole in rectangular shear panels.

As usual we have created a spreadsheet for this method.

Remember that the reduction effect of a hole should be applied to the elastic buckling allowable before material plasticity has been accounted for.

Microsoft Excel Spreadsheets

FREE ANALYSIS SPREADSHEETS 3 Over the last 10 years we have developed hundreds of spreadsheet tools to help us with our structural analysis work. We have made these available through the Abbott Aerospace web site and the XL Viking project. We have now brought them into the technical library. They have been updated, improved and the collection has been expanded to cover more analysis methods than ever before.

The XL-Viking Add-In for Excel

XL-Viking 2 We created the XL-Viking Excel add-in to satisfy our own need to make Excel a better engineering tool. XL-Viking shows your Excel Formula in a way that makes sense and brings essential new functionality to Microsoft Excel by providing an additional user interface and easy to use functions.

Technical Papers & Reports

This is our collection of public domain references. All of the material we make available has been placed in the public domain by the authors/owners. If you believe this is not the case and any of the library material is not in the public domain please let us know. If you have any reference material that you would like to see included in the library we would love to hear from you.

Market Analysis and Market Information

Our newest addition to the library is an on-going series of articles on the aircraft and aerospace market. These are part quantitative and part qualitative and introduce a new aspect to the competencies within Abbott Aerospace.
