Robust Flutter Analysis Considering Mode Shape Variations [PDF]
, 2008 A study was conducted to perform robust flutter analysis, considering mode shape variation problems. The study demonstrated that the assumption of a fixed modal base can lead to incorrect flutter results.

Shape-preserving diffusion of a high-order mode [PDF]
Optics Letters, 2013 The close relation between the processes of paraxial diffraction and coherent diffusion is reflected in the similarity between their shape-preserving solutions, notably the Gaussian modes. Differences between these solutions enter only for high-order modes.

Damage Identification of Structures Using Second-Order Approximation of Neumann Series Expansion [PDF]
Journal of Rehabilitation in Civil Engineering, 2020 In this paper, a new method proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). One of the main challenges in structural damage identification problems is the limitation in the number of used ...

Penetration performance of axisymmetric U-shape-nose grooved projectile into aluminum target: Theoretical model and experiment [PDF]
, 2018 The penetration performance of projectiles is closely related to their nose shape as it influences the kinetic energy penetration of a rigid projectile. One new type of projectile, which is entitled U-shape-nose grooved projectile, is introduced in this ...

The Mechanism of Ultra-Low Frequency Oscillations With the Same Mode Shapes
IEEE Access, 2020 The ultra-low frequency oscillation (ULFO) problem reappears in China recently. Different from the classical low frequency oscillation (LFO), the generators in ULFO have the same mode shapes, namely oscillating in the same pace.

The shape of the fundamental sloshing mode in axisymmetric containers [PDF]
Journal of Engineering Mathematics, 2015 In the paper we numerically study positions of high spots (extrema) of the fundamental sloshing mode of liquid in an axisymmetric tank. Our approach is based on a linear model reducing the problem to appropriate Steklov eigenvalue problem. We propose a numerical scheme for calculating sloshing modes and a novel method of making images of oscillating ...

Shaping Effects on Non-Ideal Ballooning Mode [PDF]
Plasma and Fusion Research, 2018 The dependence of shaping effects on the growth rate of collisionless and resistive ballooning mode (CBM/RBM) is numerically investigated. That of the drift ballooning modes (DCBM/DRBM) is also investigated by taking kinetic effects into account. Resistivity scans of linear growth rates of CBM/RBM and DCBM/DRBM in a circular geometry show that both ...
