In our previous report, the combined loading tests for bending and torsion are carried out, and the visco-elastic response is investigated by performing experiments that changes the relative angle between the principal axis of stress and the braid. Moreover, the numerical model is proposed and the validity of the model is verified by comparing it with these experimental results. On the other hand, the buckling tests are carried out by applying the axial force and the twisting moment simultaneously, and the buckling region under combined loading of axial force and torsion is verified. In this report, changing the speed of axial displacement and twisting angle, the buckling region, which is obtained by applying the axial load and the twisting moment at the same time, is examined and the relation between the buckling region and the stress relaxation is revealed.
