Abstract: Abstract In this paper, a stable node-based smoothed finite element method with PML (SNS-FEM-PML) is proposed to solve the scattering problem of a time-harmonic elastic plane wave by a rigid obstacle in two dimensions. In… read more here.

Abstract: To numerically model open-domain structures and radiation problems, an absorbing boundary condition (ABC) has to be applied to emulate infinite open space. In this letter, the split-field perfectly matched layer (PML) ABC is developed and… read more here.
