GivEn -- Shape Optimization for Gas Turbines in Volatile Energy Networks
Jan Backhaus, Matthias Bolten, Onur Tanil Doganay +19
This paper describes the project GivEn that develops a novel multicriteria optimization process for gas turbine blades and vanes using modern "adjoint" shape optimization algorithm…
Effect of local anisotropy on fatigue crack initiation in a coarse grained nickel-base superalloy
Benedikt Engel, Tilmann Beck, Nadine Moch +2
In the present work, theoretical approaches, based on grain orientation dependent Young's modulus and Schmid factor are used to describe the influence of local grain orientation on…
Combined Notch and Size Effect Modeling in a Local Probabilistic Approach for LCF
Lucas Mäde, Sebastian Schmitz, Hanno Gottschalk +1
In recent years a local probabilistic model for low cycle fatigue (LCF) based on the statistical size effect has been developed and applied on engineering components. Here, the not…
Modeling, Minimizing and Managing the Risk of Fatigue for Mechanical Components
L. Bittner, H. Gottschalk, M. Gröger +3
Mechanical components that are exposed to cyclic mechanical loading fail at loads that are well below the ultimate tensile strength. This process is known as fatigue. The failure t…
