Web1 INTRODUCTION. The theory of shear-deformable (spatial) rod formulations dates back to the pioneer works of Cosserat, 1 Timoshenko, 2 Reissner, 3 and Simo. 4 Thus, depending on the chosen literature, shear-deformable rods are called (special) Cosserat rods, 5 Simo–Reissner beams, spatial Timoshenko beams, geometrically exact beams, … WebThe theory of Kirchhoff rods as an exact consequence of three-dimensional elasticity Fabrizio Davì 1992, Journal of Elasticity A one-dimensional model of a linearly elastic thin rod is deduced from three-dimensional elasticity by regarding the Kirchhoff hypotheses as internal constraints prevailing in a three-dimensional tubular region. burgers corpus christi

The stability criteria are demonstrated on a number of examples using a simple, planar rod theory. These examples range from a classical strut under axial load to a branched tree-like structure composed of several rods.
