Buckling of some isotropic, intrinsically curved elasticas induced by a terminal twist Original Research Article

Using some isotropic, intrinsically curved elasticas as examples, this paper presents an argument elucidating that the elasticas buckle immediately as they are subjected to a terminal twist. Not only does the result proven here generalize the previous understanding of the most simplest O-ring elastica shown by Tobias et al. [1] and Qian and White [2], but also the argument is simpler and has nothing to do with solving differential equations.
