Abstract (English):
A nonlinear calculation of the stiffness of the spokes of external fixation devices in traumatology is proposed. Taking into account the geometric nonlinearity of the spoke, the finite element method is used in the calculations of stiffness and stresses arising in the spoke fasteners. Under the action of the transverse force and its preliminary tension, deflections of the spoke and stresses in the attachment points are determined.
