Arlequin Framework for Structural Transient Dynamics

Abstract eng:
Arlequin method is a modeling framework based on the combination of concurrent multiscale and multi mechanical models. It is a general application of overlapping domain decomposition. The choice of the coupling operators written in common areas between different models provide the main key to ensure the continuity of displacement, velocity, and equilibrium of forces. Using overlap coupling methods in the context of structural dynamics is advantageous when treating dissimilar domains, mainly when wave propagation between the different models is taken into consideration. In this paper we propose to couple and analyze different numerical time schemes using the Arlequin method. Numerical studies, based on multiscale and multimodel space coupling are used to exemplify the efficiency of our approach.
