The Solution of Nonlinear Time-Dependent Problems Usng Modal Coordinates.
Abstract
An algorithm for the solution of a class of nonlinear time-dependent problems using reduced modal coordinates is proposed and implemented. Example problems in one space dimension are modeled, and comparisons made to exact solutions. The results of these examples are used to make suggestions for further research. Keywords: nonlinear finite element analysis; eigenvectors; Ritz vectors; Lanczos vectors, and modal analysis.
