Cb. Yun et al., AXISYMMETRICAL ELASTODYNAMIC INFINITE ELEMENTS FOR MULTILAYERED HALF-SPACE, International journal for numerical methods in engineering, 38(22), 1995, pp. 3723-3743
This paper presents three axisymmetric infinite elements for the elast
odynamic problems in a multi-layered half-space. They are the horizont
al, the vertical and the corner infinite elements that are developed b
y using the wave functions in the function spaces derived from approxi
mate expressions of the analytical solutions. An efficient integration
procedure is proposed for calculating the element matrices involving
multiple wave components. Numerical example analyses are presented for
rigid disks on homogeneous and layered half-spaces, and for an embedd
ed caisson. The numerical results obtained show the effectiveness of t
he proposed infinite elements.
