RISAnalysis of Motions of a Semisubmersible in Sea Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The forces acting on a three-dimensional cylinder with arbitrary symmetrical cross section are derived taking into account viscous effect and applying linear-processing techniques. Then general ...
Dynamic Viscoelastic Behavior of Multiwalled Carbon Nanotube–Reinforced Magnetorheological (MR) Nanocomposites
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel class of three-phase magnetorheological (MR) nanocomposites reinforced with multiwalled carbon nanotubes. Microstructures of the nanocomposites are characterized with the scanning electron ...
Structural Damage Assessment Based on Wavelet Packet Transform
Publisher: American Society of Civil Engineers
Abstract: Wavelet transform (WT) is a mathematical tool that can decompose a temporal signal into a summation of time-domain basis functions of various frequency resolutions. This simultaneous time-frequency decomposition gives the ...
Statistical Wavelet-Based Method for Structural Health Monitoring
Publisher: American Society of Civil Engineers
Abstract: A statistical pattern classification method based on wavelet packet transform (WPT) is developed in this study for structural health monitoring. The core of this method is the WPT that has the ability of extracting minute ...
Dislocation-Induced Stress Field in Multilayered Heterogeneous Thin Film System
Publisher: American Society of Civil Engineers
Abstract: Taking advantage of the generalized Galerkin potential function and the Fourier transform, the research presented in this paper first derives the Green’s function for a multilayered heterogeneous thin film system. The ...
Transverse Vibration of an Undamped Elastically Connected Double-Beam System with Arbitrary Boundary Conditions
Publisher: American Society of Civil Engineers
Abstract: This paper presents a semianalytical method to analyze the natural frequencies and mode shapes of an undamped double-beam system, which is composed of two beams joined by a uniformly distributed connecting elastic layer, ...
