In this article, the data obtained from the uniaxial fully-reversed fatigue experiments conducted on polyether ether ketone (PEEK), a semi-crystalline thermoplastic, are presented. The tests were performed in either strain-controlled or load-controlled mode under various levels of loading. The data are categorized into four subsets according to the type of tests, including (1) strain-controlled fatigue tests with adjusted frequency to obtain the nominal temperature rise of the specimen surface, (2) strain-controlled fatigue tests with various frequencies, (3) load-controlled fatigue tests without step loadings, and (4) load-controlled fatigue tests with step loadings. Accompanied data for each test include the fatigue life, the maximum (peak) and minimum (valley) stress-strain responses for each cycle, and the hysteresis stress-strain responses for each collected cycle in a logarithmic increment. A brief description of the experimental method is also given.
本文展示了从对聚醚醚酮(PEEK,一种半结晶热塑性塑料)进行的单轴完全反向疲劳实验中获得的数据。测试在不同加载水平下以应变控制或载荷控制模式进行。根据测试类型,数据被分为四个子集,包括:(1)通过调整频率以获得试样表面名义温度升高的应变控制疲劳测试;(2)不同频率的应变控制疲劳测试;(3)无阶梯加载的载荷控制疲劳测试;(4)有阶梯加载的载荷控制疲劳测试。每次测试的附带数据包括疲劳寿命、每个循环的最大(峰值)和最小(谷值)应力 - 应变响应,以及以对数增量收集的每个循环的滞后应力 - 应变响应。还给出了实验方法概述。
