  1. A curve that minimizes bending energy; the shape that a thin flexible rod assumes when its endpoints are fixed.
    — This paper studies the snap-through of a pinned-clamped elastica when the support of the clamped end can be moved arbitrarily in plane. The universal snap curve, which describes the critical boundary conditions of the pinned-clamped elasticas, is firstly obtained by determining the saddle-node bifurcation points of the moment-rotation response curves.
  2. Connective tissue that contains elastic fibers, such as that found in blood vessels or skin.
    — That the elastica interna becomes so modified in its staining properties, so swollen as to exceed ten times the original elastica in thickness, is a fact that cannot be doubted.
