Description

Deflection is the most interactive, fast, and precise app available for structural beam analysis. Design visually and obtain engineering results, graphs, and equations instantaneously!

Simply place loads and supports on the beam, and see how it bends. Find a cross section in the built-in library, or define a custom shape. Deflection, internal stresses, and other useful results are automatically updated.

This software is the result of over six years of continuous development and innovation aimed at mechanical engineering, civil engineering, and structural engineering. This tool will help you apply beam elastic theory from day 1 as you are learning Mechanics of Materials, and it will be your go-to pocket reference any time in the future.

What’s New

Version 5.7.1

In this release we focused on reducing and improving handling of numerical error by using better numerical solver algorithms, but we also made other meaningful improvements and fixes throughout the app.

• IMPROVED: Output values close to zero will contain less numerical noise, and the app will be able to correctly solve problems with a wider range of numerical magnitudes. For example, when a support is placed extremely close of the edge of the beam relative to the total length of the beam, the internal equation matrix becomes harder to solve numerically, but now the app can solve more of these cases.
• NEW: The app will display an error message about numerical stability when numerical error prevents the app from finding a solution. If a solution was still found, but it does not pass sanity checks, a warning about stability and the failed check will also be displayed along with the unstable solution to help diagnose the problem.
• IMPROVED: We improved the usability of the sort buttons in the cross section library by adding an explicit button to sort by section name.
• IMPROVED: Added missing translations for some languages. Please let us know if you find anything that was not translated correctly.
• FIXED: Addressed many small user interface bugs througout the app.

Exceptional app!!

This is a really great app for shear and moment diagrams. Very intuitive, fabulous interface! Tried using a similar applications on the web and this beats it hands down, glad I spent the money. I'd do it again in a heartbeat. One recommendation would be to have moment in in-lb not just ft-lbs. Again great app, a winner!!!

Needs polishing

Kinda klunky interface. The calculator layout is poor. Calculator needs means of entering scientific notation. Missing aluminum extrusions. Should have a way to favorite beam shapes and add user defined ones. I prefer scientific notation normalized to be x.xx x10^x not xxx.x x10^x

Not sure why 10x length limitation.

Developer Response ,

Thank you very much for your detailed feedback and requests! We always have to make a tradeoff between polishing existing features and rolling out new ones, but over time we try to address all sharp corners, so thanks for pointing some of them out!

Regarding the 10X requirement: The equations that the app uses internally assume that the beam is "slender", meaning that the length-to-height ratio should be greater than 10. If you need to design for something shorter, you may need to use a different type of analysis tool. You can find a mention of this in the general Wikipedia article on Beam Deflection https://en.wikipedia.org/wiki/Deflection_(engineering)

Great Application for quick accurate beam evaluations

Great sanity check software before delving into a solid model evaluation
