Second Edition of our Free Textbook Now Released

January 27, 2017

We are very happy to announce that the second edition of our free engineering textbook “Analysis and Design of Composite and Metallic Flight Vehicle Structures” is now available.

We have also added many new free spreadsheets to our collection and now have over 200 free spreadsheets available to complement the textbook available in the Technical Library.  We have added many new references to the book and the library and are working hard to provide best tools and references available to structures engineers at no cost.

If you want to help, there are several different ways you can support our efforts:

  1. Consider using our engineering services for your project. We are engaged with many aircraft OEMs in many roles: Structures group leadership, Stress Analysis, Structures and Mechanical System Design, Certification Planning, Methodology definition and Test Planning and Conduct. If you like our tools you will like our engineering services.
  2. You can purchase a license for XL-Viking. We developed our Excel Add-in specifically to help engineers write and check analyses. All of our free spreadsheets use the add-in to display math. Join WS Atkins and Piper Aircraft and add XL-Viking to your software tool chest. Ensure your excel files are more accurate and display your math effortlessly.
  3. Or you can donate via Paypal or Patreon to help us develop and improve the technical library and expand the content we make available for free.

Improvements to the textbook since the first edition:

  • Stress Tensor  and Shear Stress distribution Sections now included

Textbook - Stress Tensor  and Shear Stress distribution Sections

  • Comprehensive section properties including First Moment of Area and Cozzone Shape Factor

Textbook - section properties

  • Simple Beam Equations for over 30 type of Beams

Textbook - Beam Equations

  • Over 50 brand new Free Spreadsheets linked to the Text
  • Hundreds of improvements, additions and refinements – Sections covering the use of Microsoft Excel for engineers, Improved pull through strength for composite laminates, additional guidelines for analysis of welded joints, additional of quick search links for our technical library.

This makes the textbook closer to the “one stop shop” that we always wanted it to be. Additional to future editions will include Torsion Analysis, Post-buckling, Plates under Pressure and much more.

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.

The Indispensable Tool For Engineers, Mathematicians, Scientists, Accountants and Teaching Professionals!


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.
