Self-buckling

Self-buckling refers to a phenomenon in structural engineering and materials science where a load-induced deformation occurs in a compressed structural element, such as a beam or column, without any external lateral forces being applied. Instead of failing through material yielding, the structure experiences instability due to compressive forces leading to a sudden lateral deflection. This behavior typically happens when: 1. The structural element is slender (i.e., has a high length-to-width ratio).
