The Role of Fundamental Modeling

Abstract

The difference between empirical and basic modeling and its significance is explained. The types of basic models that have been possible to develop and that are describe in the book are summarized. The starting point is a basic model for the dislocation density that is used to derive expression for tensile and creep properties. It is described how the accuracy of the basic models can be verified. For the creep models it is described that they are applicable over a wide range of temperatures and stresses that is of great value to identify operating mechanisms.
