The Life and Career of Lilly Bell: Exploring the Kink Industry

Geometric instabilities such as buckling, wrinkling, and kinking are central to the mechanics of slender structures. While classical Euler buckling has been extensively studied for straight beams, exhibit richer behavior due to the coupling between curvature and external loads. The Lilly‑Bell kink —named after the characteristic bell‑shaped profile of the filament in which it was first observed (Lilly & Bell, 2002)—represents a distinct mode of failure where a localized, high‑curvature hinge forms, often accompanied by self‑contact (Figure 1). lilly bell kink

The FE results validate the analytical criterion (1) up to moderate curvature. For higher intrinsic curvature, geometric stiffening slightly raises the kink threshold, consistent with the second‑order correction derived in Appendix B. The Life and Career of Lilly Bell: Exploring
