Implementation of strain-life fatigue parameters estimation methods in a web-based system

摘要

In order to address problems connected with the choice of a proper material during early stages of product development when limited or no experimental data on candidate materials are available, a web-based information system consisting of material properties database and expert system for the estimation of cyclic and fatigue material parameters has been established. Material properties database is user-expandable and draws mainly on existing, published literature sources and results of relevant research. Besides the well-established estimation methods and the methodology for their evaluation, the results of own research in the form of a newly proposed approach and method for the estimation of strain-life fatigue parameters as well as the methodology for the evaluation of estimation methods are incorporated in the system as well.
