Beam Buckling Fundamentals Explained

Описание: 📝In this video, SDC Verifier's CEO, Wouter van den Bos, explores the fundamentals of buckling analysis—starting from simple beam buckling and how buckling principles are applied and interpreted in standards.

You’ll learn how to:

✔️ Understand the difference between flexural, torsional, and flexural-torsional buckling
✔️See why FEA buckling models must include warping to capture realistic failure modes
✔️Recognize the role of Euler and Euler-Johnson limits in defining safety margins
✔️Compare how standards like Eurocode, AISC, and others handle buckling with varying safety factors
✔️Understand the challenges of applying linear FEA buckling analysis and why yielding effects are excluded

By the end, you’ll have a clear overview of how buckling is modeled, how safety factors are applied, and what engineers must be cautious about when interpreting FEA results.
