Journal ArticleDOI
Nonlinear Behavior of a Typical Airfoil Section with Control Surface Freeplay: a Numerical and Experimental Study
TL;DR: In this article, a three degree-of-freedom aeroelastic typical section with control surface freeplay is modeled theoretically as a system of piecewise linear state-space models.
Book
Vibration of Axially-Loaded Structures
TL;DR: In this paper, a variety of structural components are analyzed with a view to predicting their response to various (primarily axial) loading conditions, and the authors present methods by which the combined effects of vibration and buckling on various structures can be assessed.
Journal ArticleDOI
Resonances of a Harmonically Forced Duffing Oscillator with Time Delay State Feedback
TL;DR: In this article, the primary resonance and the 1/3 subharmonic resonance of a harmonically forced Duffing oscillator under state feedback control with a time delay were analyzed.
Journal ArticleDOI
Limit cycle behavior of an airfoil with a control surface
TL;DR: In this article, a three-degree-of-freedom aeroelastic model with freeplay is modeled theoretically using a small number of aerodynamic eigenmodes (i.e., a reduced order model) based upon Peters' finite-state model for two-dimensional aerodynamic flow.
Journal ArticleDOI
Vibration-based damage assessment utilizing state space geometry changes: local attractor variance ratio
TL;DR: In this article, a feature extracted from a nonlinear time series is presented within the context of vibration-based damage detection in a system, where an eight-degree-of-freedom spring-mass-damper structure is considered with damage incurred by a stiffness degradation in one spring.
