Modeling of Welded Joints in a Pyramidal Truss Sandwich Panel Using Beam and Shell Finite Elements

Ke Yuan, Weidong Zhu
Journal: Journal of Vibration and Acoustics
Article Type: Research Papers
J. Vib. Acoust. August 2021, 143(4): 041002.
Paper No: VIB-20-1333
DOI: https://doi.org/10.1115/1.4048792
Published Online: November 6, 2020
...Ke Yuan; Weidong Zhu Pyramidal truss sandwich panels (PTSPs) are widely used in engineering structures and their face sheets and core parts are generally bonded by the welding process. A large number of solid elements are usually required in the finite element (FE) model of a PTSP with welded...

Prediction of Sound Transmission Loss for Finite Sandwich Panels Based on a Test Procedure on Beam Elements

Zhongchang Qian, Daoqing Chang, Bilong Liu, Ke Liu
Journal: Journal of Vibration and Acoustics
Article Type: Research-Article
J. Vib. Acoust. December 2013, 135(6): 061005.
Paper No: VIB-12-1250
DOI: https://doi.org/10.1115/1.4023842
Published Online: June 19, 2013
...Zhongchang Qian; Daoqing Chang; Bilong Liu; Ke Liu An approach on the prediction of sound transmission loss for a finite sandwich panel with honeycomb core is described in the paper. The sandwich panel is treated as orthotropic and the apparent bending stiffness in two principal directions...

Predicting the Sound Transmission Loss of Sandwich Panels by Statistical Energy Analysis Approach

Tongan Wang, Shan Li, Shankar Rajaram, Steven R. Nutt
Journal: Journal of Vibration and Acoustics
Article Type: Research Papers
J. Vib. Acoust. February 2010, 132(1): 011004.
DOI: https://doi.org/10.1115/1.4000459
Published Online: January 8, 2010
...Tongan Wang; Shan Li; Shankar Rajaram; Steven R. Nutt A statistical energy analysis (SEA) approach is used to predict the sound transmission loss (STL) of sandwich panels numerically. Unlike conventional SEA studies of the STL of sandwich panels, which consider only the antisymmetric (bending...
