Abstract

A device is described to measure the relationship between curvature and bending moments for hollow cylinders of different sizes up to the point of collapse. The measurements for polyethylene tubes, as test material, and stalks of Triticum aestivum and Secale ancestrale reveal a pronounced nonlinear relationship characterizing local buckling. Refinement of a previous theoretical approach considering also shear strains leads to an adequate description of the data. The analysis allows determination of the Young's moduli of elasticity not only in longitudinal but also in transverse direction.
