The Earthquake Engineering Online ArchiveAccuracy Control of a Direct Spectral Method for Nonlinear Elastic ProblemsWisniewski, Krzysztof; Taylor, Robert L. UCB/SEMM-1989/21, Dept. of Civil Engineering, University of California, Berkeley, 1989-11, 27 pages An accuracy control procedure for nonlinear elastic problems discretized by the direct spectral method is presented. Two forms of the Lax-Richtmyer conditions for convergence are discussed and an error estimation formula suitable for numerical applications is given.
