Abstract: The concept of time interval response spectrum is introduced for characterizing the damage potential or the likelihood of a waveform to cause multiple mode response. By modifying slightly a ...

Abstract: A computational study of the multirow interaction mechanisms has been carried out for a one-and-a-half stage (NGV-rotor-stator) transonic turbine. In addition to measurable subharmonic unsteadiness ...

Abstract: Multistage effects on both aerodynamics and aeromechanics have been identified as significant. Thus, design optimizations for both aerodynamic performance and aeromechanical stability should be done ...

Abstract: One of the outstanding issues in turbomachinery aeromechanic analysis is the intrarow interaction effects. The present work is aimed at a systematic examination of rotor-stator gap effects on ...

Abstract: The bidding decision is a complex problem affected by numerous factors. The current study collected a list of determining factors from the results of past research and opinions of six experienced practitioners in competitive ...

Abstract: This paper proposes a scale-dependent model to investigate the dynamic-pull-in characteristics of a functionally graded carbon nanotubes (FGCNTs) reinforced nanodevice with a piezoelectric layer. Based on nonlocal beam ...

Abstract: The problem of disturbance decoupling is formulated and solved for continuous-time linear systems in which feedforward of disturbance input and its derivatives is allowed. The problem of disturbance ...

Abstract: Computations of unsteady flows due to inlet distortion driven blade vibrations, characterized by long circumferential wavelengths, typically need to be carried out in multi-passage/whole-annulus ...

Abstract: A laboratory study was conducted to investigate the behavior of a soft compacted clayey soil subjected to repeated loading. The work was part of a comprehensive investigation of the Low Track Modulus section at the Facility ...

Abstract: The lack of an appropriate three-dimensional constitutive relation for stress in passive ventricular myocardium currently limits the utility of existing mathematical models for experimental and ...
