An adaptive perfectly matched layer finite element method for acoustic-elastic interaction in periodic structures
Sijia Li, Lei Lin, Junliang Lv
This paper considers the scattering of a time-harmonic acoustic plane wave by an elastic body with an unbounded periodic surface. The original problem can be confined to the analys…
Numerical method for the inverse scattering by random periodic structures
Yi Wang, Lei Lin, Junliang Lv
Due to manufacturing defects or wear and tear, industrial components may have uncertainties. In order to evaluate the performance of machined components, it is crucial to quantify…
An Adaptive Finite Element DtN Method for the Acoustic-Elastic Interaction Problem in Periodic Structures
Lei Lin, Junliang Lv
Consider a time-harmonic acoustic plane wave incident onto an elastic body with an unbounded periodic surface. The medium above the surface is supposed to be filled with a homogene…
Alternately-optimized SNN method for acoustic scattering problem in unbounded domain
Haoming Song, Zhiqiang Sheng, Dong Wang +1
In this paper, we propose a novel machine learning-based method to solve the acoustic scattering problem in unbounded domain. We first employ the Dirichlet-to-Neumann (DtN) operato…
