On the estimation of cyclic material properties - Part 1: Quality of known estimation methods Dedicated to Professor Dr.-Ing. Harald Zenner on the occasion of his eightieth birthday

摘要

A large variety of methods for estimating cyclic material properties from quasi-static material properties can be found throughout the literature. Therefore, the user usually faces the problem of determining which methods would best suit his purpose. To help answer this question, a massive database containing test results from quasi-static and cyclic tests is gathered and used for a quality rating of the different methods. This rating results in the recommendation to use the uniform material law for steel materials, the modified park-song's method for wrought aluminum and the method of variable slopes 2006 for thin steel sheets. In addition, the accuracy of these estimation methods is compared to experimental results using deviation ranges in the total strain life curve and in the cyclic stress-strain curve.
