Descriptions
A numerical method for the elastic wave propagation problems involving infinite continuous systems has been proposed. In the method, the fictitious boundary consists from two kinds of mixed boundaries. Results obtined by the proposed method are compared with those with Lysmer's viscous boundaries. It is shown that the 2-step successive averaging method gives results almost the same as those with Lysmer's viscous boundaries.
