  • GS33 Buckling Behavior of Catheter Reinforced with Braid : Hydrous Effect on the Buckling Region under Proportional Loading for Compression and Torsion

抄録

In our previous report, the buckling region, which is obtained by applying the axial load and the twisting moment at the same time, was examined by changing the speed of axial displacement and twisting angle, and the relation between the buckling region and the stress relaxation was revealed. If we consider the actual surgical operation, the catheter is used under the wet condition. However, in these studies, the experiments were carried out under the arid condition without including liquid, and the hydrous effect had not been considered yet. So, in this paper, the hydrous effect on the buckling behavior is examined under the combined loading of compression and torsion.
