A New Method for Fatigue Testing and Data Presentation: an Ilustration on Some Metallic Ceramic and Polymer Materials

摘要

In this study a new method for fatigue testing and data presentation has been proposed, which is based on a reduced number of data readings during a fatigue test. This method represents the experimental results obtained at a given stress range linearly and shows possibilities for shortening testing times and making fatigue analyses and predictions more precise. The paper describes how the method works for representing fatigue in a high-strength spring steel. Some preparatory work has been done towards showing the applicability of the proposed method to different kinds of Al_2O_3 ceramic and a PC polymer.
