- Abstract
Analyzing the semi-discretized equations of motion has a fundamental role in structural dynamic analysis. Though time integration is the widely accepted approach for these analyses, the stability and accuracy of the responses computed by time integration are yet unpredictable. Considering linearly-elastic/perfectly-plastic dynamic systems, recently two independent methods for preserving responses' convergence is presented. In this paper these two methods are first reviewed. Then implementing a recent round off reduction technique, a reliable method for preserving responses' convergence is attained. Implementing the new method for analyzing a simple linearly-elastic/perfectly- plastic dynamic system with several different integration methods reveals that for the systems under consideration, the proposed method preserves responses' convergence, regardless of the integration method.
