Abstract

The tolerated acute angle in kinking constitutes a good relative measure for kinking resistance. It is quite a constant parameter for steel wires (about 30 degrees) and for titanium wires (about 80 degrees). The force required to bend a wire to a specific angle depends only on the stiffness of the wire. This means that kinking resistance is also a function of stiffness.

摘要

扭结时的耐受锐角是抗扭结性能的良好相对度量。对于钢丝（约30度）和钛丝（约80度）来说，这是一个相当恒定的参数。将钢丝弯曲到特定角度所需的力仅取决于钢丝的刚度。这意味着抗扭结性能也是刚度的函数。
