Abstract

This paper details the development and assessment of a new empirical creep model that belongs to the limited ranks of models reproducing full creep curves. The important features of the model are that it is fully standardised and is universally applicable. By standardising, the user no longer chooses functions but rather fits one set of constants only. Testing it on 7 contrasting materials, reproducing 181 creep curves we demonstrate its universality. New model and Theta Projection curves are compared to one another using an assessment tool developed within this paper.

摘要

本文详细介绍了一种新的经验蠕变模型的开发与评估，该模型属于能够再现完整蠕变曲线的有限模型类别。该模型的重要特点是它完全标准化且普遍适用。通过标准化，用户不再需要选择函数，而只需拟合一组常数。我们在7种不同材料上对其进行测试，再现了181条蠕变曲线，从而证明了它的通用性。使用本文开发的评估工具，将新模型与西塔投影曲线进行了相互比较。
