| 摘 要： | 本文将离散的局部透射边界与集中质量有限元方法相结合,用于模拟粘弹性成层介质中的稳态波动。并以一个受集中线力作用的粘弹性土层的出平面稳态波动为例,将有限元模拟与解析方法的计算结果进行比较,验证此模拟方法的有效性,着重显示在频域中实现高阶透射的可能性。

| Abstract: | In this paper,a discrete local transmitting boundary is combined with a lumped-mass finite element technique for simulating steady wave motion in the visco-elastic layered medium.By an example of the anti-plane steady waw motion in a visco-elastic layer on which a concentrated line load was applied,the calculated re- sults of the finite element simulation are compared with those of the analytical method in order to test the effi- ciency of this simulation.The possibility of high order in frequency domain is shown especially. |
