Abstract

In this paper, the propagation of 2-D, transversal elastic waves is simulated by using the network method. The spatially discretized wave equation is the basis for designing the model of the volume element which contains as many components as addends in the governing equation. The whole network model, including the boundary conditions, is run in a suitable circuit simulation code such as PSpice with a relatively small computational time. The rules for the design are very few since there is a special component in the libraries of such codes, named controlled source, that is capable of implementing any kind of non-linearity or coupled term in the equation. The design routines as well as those required for the subsequent post-processing of output data are carried out by MATLAB. After the study and simulation of a standard case, in order to compare the network solutions with those obtained by the finite-difference explicit method, two problems are presented using the known Ricker pulse as excitation.
