- 8.2: Trefftz Condition for Stability
- In 1933 the German scientist Erich Trefftz proposed the energy criterion for the determination of the stability of elastic structures. We shall explain this criterion on a simple example of a one-degree-of-freedom structure.
- 8.3: Stability of Elastic Column Using the Energy Method
- The Trefftz condition for stability can now be extended to the elastic column subjected to combined bending and compression.
