In-Plane Stability of Fixed-Fixed Heterogeneous Curved Beams under a Concentrated Radial Load at the Crown Point

Abstract

The paper by Kiss and Szeidl (2014) is devoted to the stability problem of pinned-pinned shallow curved beams provided that the beam is made of a heterogeneous material and the radius of curvature is constant. The present paper is concerned with the same issue given that the beam is fixed-fixed. Making use of the model presented in Kiss and Szeidl (2014) we aim to (a) determine the critical value of the central load (applied at the crown point) and (b) compare the results with those valid for homogeneous curved beams.
