Explicit eigenanalysis in structural dynamics using viscous dynamic relaxation method

This paper introduces a novel application of the dynamic relaxation (DR) method with viscous damping for solving eigenvalue problems arising from finite element simulation of structural dynamics. The scheme is a simple vector iteration solver based on the fundamental concepts of structural dynamics,...
