Lebensdauervorhersage fur partikelverstaerkte Aluminiumlegierungen unter Beruecksichtigung der mikrostrukturellen Aspekte der Schaedigung (Working Life Predictions for Particle-Strengthened Aluminum Alloy with Regard to Microstructural Aspects of Deterior

摘要

The goal of the study is to produce a reliable working life assessment for construction components made out of metal-matrix compounds with complex micro structures. In addition, the results should come from texture analysis, continuum-mechanical observations and., therefore, influence deterioration testing in preserved working life prediction concepts, thereby creating the basis for an improved application of these concepts for materials with heterogenous micro structures. The method employed is the Finite Element Method (FEM), which is outlined in detail in the second chapter. The qualification of the compound 6061/Al 203 also is discussed as the beginning of chapter five, which concludes with working life predictions for oscillating strain.
