Pincheira, "Domain Decomposition Methods with Nonlinear Localization: Influence of the Decomposition Choice on the Results", in , (Editors), "Proceedings of the Fifth International Conference on Parallel, Distributed, Grid and Cloud Computing for Engineering", Civil-Comp Press, Stirlingshire, UK, Paper 13, 2017. doi:10.4203/ccp.111.13

Keywords: structures, multiscale analysis, domain decomposition, nonlinear structural analysis, post-buckling, nonlinear localization.

Summary

The efficiency and robustness of a mixed domain decomposition method with nonlinear localization has being presented in different works. These strategies allow to handle arbitrary large load increments in one step. In this paper, we are presenting some limitations of the nonlinear localization techniques, specially when treating complex industrial structures such a stiffened panel, where the capabilities of the strategy are lost. Also, a proposition for improvement of the strategy, consisting on a two-scale approximation of the Robin parameter of the strategy, is presented.
