Wave--a Computer Program for One-dimensional Stress Wave Analysis in a Time-dependent Inelastic Rock Using a Generalized Voigt Model.
NTIS: PB 214 236 :31 pages
A Fortran IV computer program entitled wave, which employs an explicit finite difference scheme for solving the one-dimensional wave equation for a time-dependent inelastic rock has been developed. The viscoelastic properties of the rock are represented in terms of a generalized voigt model. The theory on which the computer program is based is rederived and a short description of the program is given. The computer program input instructions, a listing of the computer program, and example problems with required input and subsequent printed output are presented in appendixes. In the example problems, calculated results are free of spurious oscillations which occur in certain other methods of numerical calculation, notably the extended ritz method.
