ISO 1099:2017规定了在环境温度下对金属试样进行轴向、恒定振幅、力控制疲劳试验的条件,无需故意引入应力集中。在使用本文件时,测试的目的是提供疲劳信息,例如在不同应力比下,给定材料条件(如硬度和微观结构)下施加的应力与失效循环次数之间的关系。
虽然描述了圆形和矩形横截面试样的形式、制备和测试,但本文件不包括部件测试和其他特殊形式的测试。
ISO 1099:2017 specifies the conditions for conducting axial, constant-amplitude, force-controlled, fatigue tests at ambient temperature on metallic specimens, without deliberately introduced stress concentrations. The object of testing while employing this document is to provide fatigue information, such as the relation between applied stress and number of cycles to failure for a given material condition, such as hardness and microstructure, at various stress ratios.
While the form, preparation and testing of specimens of circular and rectangular cross-section are described, component testing and other specialized forms of testing are not included in this document.
