Abstract

In this study, the mechanical properties of a balloon catheter were examined under tensile loading condition. In the joint part, the outer tube fractured first, while in the shaft part, the inner tube fractured. The load-displacement curve of the joint part was well predicted using the Todo's model. The stress-strain curves of the inner and outer tubes were also well predicted using the total deformation theory with use of an exponential function for the stress-plastic strain relation.
