A node-based smoothed finite element method with stabilized discrete shear gap technique for analysis of Reissner-Mindlin plates
Hung Nguyen-Xuan,Hung Nguyen-Xuan,Timon Rabczuk,Nhon Nguyen-Thanh,Trung Nguyen-Thoi,Trung Nguyen-Thoi,Stéphane Bordas +6 more
TL;DR: In this paper, a node-based smoothed finite element method (NS-FEM) using 3-node triangular elements is formulated for static, free vibration and buckling analyses of Reissner-Mindlin plates.

Improving High-Speed Machining Material Removal Rates by Rapid Dynamic Analysis
TL;DR: In this article, three advances toward the rapid identification of the tool point frequency response and corresponding stable cutting parameters are described: 1) stable speeds determination using noncontact periodic impulsive excitation of tool point (produced by spindle rotation and a stationary magnet) in conjunction with once-per-revolution sampling, 2) Receptance Coupling Substructure Analysis for the analytic prediction of the Tool Point response, and 3) once per-revolution sample of the audio signal during cutting to determine stability behavior.
Dissertation
Piezoelectric-based in-situ damage detection of composite materials for structural health monitoring systems
TL;DR: Spearing et al. as discussed by the authors presented the conclusions of an analytical and experimental survey of candidate methods for in-situ damage detection in composite materials and verified experimentally by using piezoelectric patches as actuators and sensors.

Quantification and localisation of damage in beam-like structures by using artificial neural networks with experimental validation
Melin Sahin,R.A. Shenoi +1 more
TL;DR: In this paper, the authors used a combination of global (changes in natural frequencies) and local (curvature mode shapes) vibration-based analysis data as input in artificial neural networks (ANNs) for location and severity prediction of damage in beam-like structures.

The μ-flown: A novel device for measuring acoustic flows
Hans-Elias de Bree,P.J. Leussink,T. Korthorst,Henri Jansen,Theo S.J. Lammerink,Miko Elwenspoek +5 more
TL;DR: In this paper, the micro-flown or μ-fly sensor was developed to measure the acoustic flow of an acoustic wave, which consists of two elements, acoustic pressure and acoustic flow.
