标准范围

本文件规定了在不故意引入应力集中的情况下，对金属试样进行扭转、恒定振幅、名义弹性应力疲劳试验的条件。试验通常在环境温度或空气中的高温下进行，方法是在试样的纵轴周围施加一个纯电偶。虽然本文件描述了圆形截面和管状截面试样的形式、制备和测试，但不包括部件和其他特殊类型的测试。同样，在恒定载荷下进行的低周扭转疲劳试验-振幅角位移控制也被排除在外，它会导致几千个周期内的故障。

This document specifies the conditions for performing torsional, constant-amplitude, nominally elastic stress fatigue tests on metallic specimens without deliberately introducing stress concentrations. The tests are typically carried out at ambient temperature or an elevated temperature in air by applying a pure couple to the specimen about its longitudinal axis.While the form, preparation and testing of specimens of circular cross-section and tubular cross-section are described in this document, component and other specialized types of testing are not included. Similarly, low-cycle torsional fatigue tests carried out under constant-amplitude angular displacement control, which lead to failure in a few thousand cycles, are also excluded.
