| Buckling of a Thin Column.MP4 |
|
|
|
|
|
|
|
|
Comparison of two thin columns with identical cross-sectional area but different cross-sectional shapes. Euler buckling equation shows how different area moments of inertia affect predicted buckling loads Note: during the calculations, I wrote height of stick 1 as being 4m when it is really4mm. It is correct in the next line and the result is correct.

This video shows bifurcation and instability experiments of elastic structures subject to tensile dead load. This research was published in the journal Proceedings of the Royal Society A in the paper: Structures buckling under tensile dead load by D. Zaccaria, D. Bigoni, G. Noselli and D. Misseroni. The doi link for the article is dx.doi.org
