Adjoint Method to Calculate Shape Gradients of Failure Probabilaties for Turbomachinery Components
Hanno Gottschalk, Mohamed Saadi, Onur Tanil Doganay +2
In the optimization of turbomachinery components, shape sensitivities for fluid dynamical objective functions have been used for a long time. As peak stress is not a differential f…
Probabilistic LCF Risk Evaluation of a Turbine Vane by Combined Size Effect and Notch Support Modeling
Lucas Mäde, Sebastian Schmitz, Georg Rollmann +2
A probabilistic risk assessment for low cycle fatigue (LCF) based on the so-called size effect has been applied on gas-turbine design in recent years. In contrast, notch support mo…
Probabilistic Analysis of LCF Crack Initiation Life of a Turbine Blade under Thermomechanical Loading
Sebastian Schmitz, Georg Rollmann, Hanno Gottschalk +1
An accurate assessment for fatigue damage as a function of activation and deactivation cycles is vital for the design of many engineering parts. In this paper we extend the probabi…
Risk estimation for LCF crack initiation
Sebastian Schmitz, Georg Rollmann, Hanno Gottschalk +1
An accurate risk assessment for fatigue damage is of vital importance for the design and service of today's turbomachinery components. We present an approach for quantifying the pr…
