Curvature-induced stiffening of a fish fin
WebA fish fin is thin, and yet not floppy when it pushes on the surrounding water for propulsion. We show that fish could modulate fin stiffness by changing its curvature. The rays contribute to its bending stiffness in the way an elastic beam would, but it is the curvature that substantially increases its stiffness by engaging the intervening ... WebAug 21, 2016 · How fish modulate their fin stiffness during locomotive manoeuvres remains unknown. We show that changing the fin's curvature modulates its stiffness. Modelling the fin as bendable bony rays held together by a membrane, we deduce that fin curvature is manifested as a misalignment of the principal bending axes between neighbouring rays. …

How fish modulate their fin … WebAug 21, 2016 · Fish behaviour and its ecological niche require modulation of its fin stiffness. Using mathematical analyses of rayed fish fins, we show that curvature transverse to the rays is central to fin stiffness. We model the fin as rays with anisotropic bending that are connected by an elastic membrane. For fins with transverse curvature, external loads …
