Parallel Dynamic Non-Linear Analysis of Reinforced Concrete Plates


This paper on "Parallel Dynamic Non-Linear Analysis of Reinforced Concrete Plates" was presented at the NAFEMS World Congress on Design, Simulation & Optimisation: Reliability & Applicability of Computational Methods - 9-11 April 1997, Stuttgart, Germany.

Abstract

This paper shows how parallel processing may improve the computational efficiency of the transient dynamic non-linear analysis of reinforced concrete plates subjected to blast loading. The results presented in the paper are based on a parallel scheme for a time marching procedure using the explicit Newmark's algorithm. It is shown that very high computational efficiency may be obtained by decomposing the finite element mesh into a number of subdomains for distributed analysis on multiple processors. Through examples it is demonstrated how this efficiency depends on the problem size (i.e. the level of refinement of the problem idealisation), the number of sub-domains and the status of the analysis with regards to the states of the material.
