What are the common fatigue test applications and standards?

Abstract: 本文介绍了疲劳测试的基本概念、应用和相关标准。疲劳测试用于评估材料在循环载荷条件下的耐久性,旨在确定其承受反复加载和卸载(如拉伸、压缩、弯曲或扭转)的能力。测试通常包括拉伸-拉伸、压缩-压缩以及拉伸-压缩加载模式,以评估材料的疲劳寿命和抗裂性。常见应用包括种植牙、聚合物基复合材料、金属复合材料、橡胶和弹性体的疲劳测试,以及高温和低温条件下的材料测试。文章还列出了一些主要的疲劳测试标准,如ASTM D3479(聚合物基复合材料的拉伸-拉伸疲劳试验)和ISO 14801(牙科种植体的动态负载测试),这些标准提供了规范的测试方法,以确保测试结果的准确性和一致性。

fatigue test

Fatigue testing helps determine a material's ability to withstand cyclic fatigue loading conditions. By design, materials are selected to meet or exceed expected service loads in fatigue testing applications. Cyclic fatigue testing involves repeated loading and unloading of stresses in tension, compression, bending, torsion, or combinations of these. Fatigue tests are usually loaded in tension-tension, compression-compression and tension-compression followed by reverse loading.

Typically, the purpose of fatigue testing is to determine the life of a material under cyclic loading, however, fatigue strength and crack resistance are also commonly sought values. The fatigue life of a material is the total number of cycles the material can withstand under a single load case.
