title: [The distribution of material density and mechanical stress in the human radius during bending (author's transl)].
abstract: In a hypothetical mechanical system generated by computer, various kinds of loads are applied to 78 human Radii. The torque and bending stresses occuring at the surfaces of 390 cross-sections of the bone, taken from sites spaced at regular intervals along the bone shaft, are calculated and plotted. In this system, a load is rotated around the point of gravity of a cross-section. For each possible position of the load during the rotation, the total stresses occuring at the surfaces of the cross-sections are calculated and the position of the load causing minimal stress is determined. This position will be called "the most advantageous bending-plane". Furthermore, the variation of the cross-sectional surfaces and the moments of inertia are analysed.
