From Phenomenology to a Nonlinear Model of Dynamic Snap-Through of an Elastica
Chiraprabha Bhattacharyya, Ramsharan Rangarajan
Rotating the clamped ends of a buckled elastica induces a snap-through instability. Predicting the limit point and determining the equilibria at the start and end of the snap are r…
