Strain-Based Fatigue Data for Ti-6Al-4V ELI under Fully-Reversed and Mean Strain Loads

This article presents the experimental data supporting the study to obtain the mean strain/stress effects on the fatigue behavior of Ti-6Al-4V ELI. A series of strain-controlled fatigue experiments on Ti-6Al-4V ELI were performed at four strain ratios (-1, -0.5, 0, and 0.5). Two types of data are included for each specimens. These are the hysteresis stress-strain responses for the cycle in a log10 increment, and the maximum and minimum stress-strain responses for each cycle. Fatigue lives are also reported for all the experiments.

本文提供了支撑相关研究的实验数据，该研究旨在明确平均应变/应力对Ti-6Al-4V ELI疲劳行为的影响。本研究针对Ti-6Al-4V ELI开展了一系列应变控制疲劳实验，设置了-1、-0.5、0、0.5共4种应变比。每个试样包含两类数据：其一为以log10为增量的循环滞后应力-应变响应，其二为每个循环的最大与最小应力-应变响应。所有实验均记录了疲劳寿命。
