8.1: Prelude to Stability of Elastic Structures
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.
8.4: Effect of Structural Imperfections
8.5: Stability in Tension
8.6: Plastic Buckling of Columns
8.7: Mode Transition (Advanced)
