  local transmitting boundary
A discrete local transmitting boundary is combined with a lumped-mass finite element technique for simulating steady SH wave motion in a layered and unbounded medium.
      


Analysis on accuracies of the Extrapolation Boundary and Para axial Approximation has led to that their drawbacks in transmitting waves of large incident angles are originated from using a single transmitting direction. A new idea to express the incident waves in the neighborhood of a boundary point by the sum of plane waves at predetermined incident angles is then presented to eliminate the shortcoming. A new type of local transmitting boundaries set up using the idea enjoys a dramatic reduction of the reflection...

Analysis on accuracies of the Extrapolation Boundary and Para axial Approximation has led to that their drawbacks in transmitting waves of large incident angles are originated from using a single transmitting direction. A new idea to express the incident waves in the neighborhood of a boundary point by the sum of plane waves at predetermined incident angles is then presented to eliminate the shortcoming. A new type of local transmitting boundaries set up using the idea enjoys a dramatic reduction of the reflection from the boundary over the entire range of incident angles. This idea is concisely illustrated for simulation of the steady-state SH wave motion and its implication for establishing a high accurate and stable local transmitting boundary in general cases are briefly discussed.

离散局部透射边界和旁轴近似的精度分析表明,它们所以缺乏透射大角度入射波的能力乃是源于采用单一的透射方向。本文提出将边界节点附近的入射波表示为一系列预定入射角的平面波的叠加以消除这一缺点。在这一思想上建立的局部透射边界能够在全部入射角范围内减小反射。通过模拟稳态SH波动简要地阐明了上述思想及其在建立高精度、稳定的局部透射边界中的意义。

A local transmitting boundary is combined with a lumped-mass finite element technique to form a mechanical model simulating the near field steady wave motion . The motion of any node in the model only couples with those in its neighborhood. This characteristic results in a simple and effective algorithm for the finite element simulation. In this paper, the method is illustrated by an example of the anti-plane wave motion in an elastic layer fixed at its base and accuracies of a new local transmitting boundary...
