RISInvestigating Discrepancies in Vibration Bending Fatigue Behavior of Additively Manufactured Titanium 6Al-4V
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibration bending fatigue life uncertainty of additively manufactured titanium (Ti) 6Al-4V specimens is studied. In this investigation, an analysis of microscopic discrepancies between ten fatigued specimens paired by ...
Active Subspace Development of Integrally Bladed Disk Dynamic Properties Due to Manufacturing Variations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The impact of geometry variations on integrally bladed disk eigenvalues is investigated. A large population of industrial bladed disks (blisks) are scanned via a structured light optical scanner to provide as-measured ...
Gaussian Stochastic Process Modeling of Blend Repaired Airfoil Modal Response Using Reduced Basis Mode Shape Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A machine learning (ML) approach is developed to predict the effect of blend repairs on airfoil frequency, modal assurance criterion (MAC), and modal displacement vectors. The method is demonstrated on a transonic research ...

Optimization of Airfoil Blend Limits With As-Manufactured Geometry Finite Element Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional airfoil blend repair limits are established using nominal, design intent geometry. This convention does not explicitly consider the inherent blade-to-blade structural response variation associated with geometric ...
