Abstract

Elastomeric materials are often used as components that undergo cyclic loading during application, such as tires, seals, and hoses. For this reason, the long-term performance, or more precisely the crack growth behavior, is of great importance. Even though several studies investigated the fatigue behavior of rubber materials during the last 80 years, this topic is still widely under discussion and remains of great interest among scientists. Mars and Fatemi reviewed the developments of the field in the beginning of 2000, however, this paper considers the overall development including new findings to serve as a guide for further investigations in the field of fatigue of elastomers. For this purpose, the usual measurement methods and their evaluation, as well as the most important factors influencing the fatigue behavior, like the formulation of the rubber compound or the application and testing conditions, are explained in detail. Furthermore, an outlook is given on parameters that still need to be scientifically investigated, such as the influence of filler orientations or the selected manufacturing method, in order to fully understand fatigue crack growth.

摘要

弹性体材料通常用作在应用过程中承受循环载荷的部件，例如轮胎、密封件和软管。因此，长期性能，或更准确地说裂纹扩展行为非常重要。尽管在过去 80 年里有几项研究调查了橡胶材料的疲劳行为，但这个话题仍然受到广泛讨论，并且仍然受到科学家的极大兴趣。Mars和Fatemi在2000年初回顾了该领域的发展，然而，本文认为总体发展包括新的发现，可以为弹性体疲劳领域的进一步研究提供指导。为此，通常的测量方法及其评估，以及影响疲劳行为的最重要因素，如橡胶化合物的配方或应用和测试条件等都进行了详细解释。此外，还对仍需要科学研究的参数进行了展望，例如填料取向或所选制造方法的影响，以便充分了解疲劳裂纹扩展。
