Textbook Update – Second Edition
In my spare time I have been working on the next edition of the textbook. I was aware that the first edition was ‘incomplete’. In essence, every edition will be incomplete as there is always something more we can add. The First Edition was less comprehensive than I had hoped, but we had to release something at some point and the First Edition was a compromise. The Second Edition will be a compromise as well, but it will be a compromise I am much happier with.
In the Second Edition, we will cover some more subjects:
Section properties: In this section, we define the first moment of area of the shape as well as the typical section properties. The first moment of area is used to calculate the actual elastic shear distribution in a cross section and is also used to define the plastic bending section shape factor used in the Cozzone method.
Beam Analysis: We will include the definition of shear force, bending moment and deflection for typical beam configurations and there will be a spreadsheet link for each method. This has taken a long time to implement but I believe it will be very useful.
Stress Analysis: The section that I regretted most not including in the original edition was a section on basic stress tensors and material failure criteria. This section is aimed at isotropic materials (the equivalent plane strain failure criteria is already defined in the composite section of the first edition). This will come with links to spreadsheets for all of the methods.
Using Excel: I have been using Microsoft Excel to write stress reports for two decades and it is my platform of choice. Like the textbook, it is a compromise. But we have developed a way of working with Excel that we think makes it the best choice for most analyses and report writing. In the second edition of the book I have tried to explain the golden rules we use when using Excel as a report writing tool. This is the philosophy that we apply to all of the standard analysis sheets.
General updates and improvements: As always we are beholden to the generosity of the engineering community and you have provided valuable feedback to help us catch errors and make improvements to the First Edition. I have lost count of the number of tweaks we have made to the existing content but we are somewhere in the hundreds.
I regret that I can’t find more time to work on the book – it is a source of interest and enjoyment for me and I am looking forward to getting the Second Edition done so I can start to work on the new content and methods for the Third Edition.
If there is anything you would like to see included that is not in the first edition or mentioned above please let me know.
