The physical properties of catheter, which made of soft nylon resin and is reinforced with thin stainless wires called braid, are investigated in this paper. In our previous study, the buckling tests under uni-axial loading have been carried out with various speeds, and the relation between the phenomenon of stress relaxation and the buckling load has been revealed. In this paper, the buckling tests are carried out with the conditions that the axial force and torsion are applied simultaneously, and the buckling region under combined loading is examined by changing the ratio of axial force and torsion. Moreover, the relation between the buckling behavior and the stress relaxation is researched by changing the speed of axial force and torsion.
