Effect of Ritz Vectors on Random Seismic Response of Cantilever Beam
Springer Science and Business Media LLC - Tập 7 - Trang 321-333 - 2019
Xiaoshuang Han, Bo Zhou, Wie-Min Gho, Soon-Keat Tan
To understand the effect of Ritz vectors on the random seismic response of non-uniform cantilever beam, the following works are performed: Firstly, the equation of random seismic response of non-uniform cantilever beam based on Hamilton theory is presented. The solution is derived using the combined classical Ritz and pseudo-excitation method. Secondly, by considering the principle of virtual disp...... hiện toàn bộ
Static Buckling Analysis of FG Sandwich Nanobeams
Springer Science and Business Media LLC - - Trang 1-26 - 2023
Bui Van Tuyen, Gia Thien Luu
This paper proposes a third-order shear deformation theory to study the static buckling of FG sandwich nanobeams, where the core layer of the beam has hollows in the z direction, and the two sandwich types mentioned in this paper are the hardcore and softcore types. Based on nonlocal theory, the size effect is considered, and two different solutions, as an exact solution and an approximate solutio...... hiện toàn bộ
Hierarchical Bayesian Model Updating Using Modal Data Based on Dynamic Condensation

Numerical Tuning of Nonlinear Energy Sinks in Shear Buildings
Springer Science and Business Media LLC - - Trang 1-14 - 2023
Eliot Motato, Fabio G. Guerrero
A nonlinear energy sink (NES) is an energy-dependent absorber that has gained popularity as it can resonate with any mode of the primary structure. An NES mitigates the primary structure’s vibrations in two different forms. In the first form, a one-directional energy flow is generated from the structure to the NES where the vibrating energy is consumed by the absorber damping. In the second form, ...... hiện toàn bộ
Analysis of Quasi waves in Orthotropic Layer Bonded Between Piezoelectric Half-Spaces with Imperfect and Sliding Interfaces
Springer Science and Business Media LLC - - Trang 1-26 - 2023
Pato Kumari, Rupali Srivastava
The objective of present work is to investigate seismic wave reflection/transmission in an orthotropic layer bonded between two piezoelectric half-spaces in presence of an imperfect corrugated superstratum and sliding lower interface. Closed form analytical expressions for displacement field, electric potential, and velocity profile of quasi seismic waves are deduced for respective geomedia using ...... hiện toàn bộ
Performance Evaluation of Low- and High-Contact Ratio Spur Gears: Dynamic Response and Bending Strength
Springer Science and Business Media LLC - Tập 10 - Trang 1337-1347 - 2022
Oguz Dogan
High-contact ratio gears are very important components for power transmission systems as they increase the load-carrying capacity of the gear wheel as well as reduce the dynamic loads and accordingly low vibration and noise. However, it has been observed that there are very few studies in the literature investigating the dynamic performance of high-contact spur gears at different operating speeds ...... hiện toàn bộ
Accuracy and Efficiency Analysis of the Beam Elements for Nonlinear Large Deformation
Springer Science and Business Media LLC - Tập 11 - Trang 319-328 - 2022
Zhen Wang, Changle Xiang, Hui Liu, Ming Liu
The purpose of this paper is to study that which beam element should be adopted to achieve the required high accuracy and efficiency in different projects. Three kinds of beam elements commonly used to analyze the nonlinear dynamics of flexible multibody systems are compared and analyzed, which are fully parameterized beam and gradient-deficient beam elements based on the absolute nodal coordinate...... hiện toàn bộ
Acoustic Radiation of Vibrating Bodies near Rigid Planes

Reconstruction of the Regional Response of a Bridge Deck Based on Finite-Element Analysis
Springer Science and Business Media LLC - - Trang 1-16 - 2023
Weimin Zhang, Xiayi Zheng, Kan Liu, Jian Chen
Bridges play a crucial role in ensuring regional connectivity and traffic safety. However, their vulnerability to environmental factors and material degradation can lead to varying degrees of damage. The bridge structural health monitoring system (SHMS) has emerged as an efficient and intelligent alternative to traditional detection methods to tackle these challenges. This paper presents an improv...... hiện toàn bộ
