An algorithm to solve transient structural non-linear problems for non-matching time-space domains

This paper presents a new transient algorithm to couple sub-domains having non-matching time and space interfaces. The time integrators in each of the sub-domains are of the Newmark family but can be different. The method is also developed for non-linear explicit transient computations for which the time steps are not constant. A number of examples are presented which illustrate the interest, quality and the efficiency of the proposed method. (C) 2003 Published by Elsevier Science Ltd.
