Title: | Multiscale modelling of masonry structures using domain decomposition techniques | Authors: | HEYENS, Koen VANDOREN, Bram Schueremans, Luc |
Issue Date: | 2011 | Source: | Oñate, Eugenio & Owen, David Roger Jones (Ed.) Proceedings of the 11th International Conference on Computational Plasticity (COMPLAS XI): vol. 1. | Abstract: | This paper describes the application of a domain decomposition technique for multiscale modelling of fracture behaviour in masonry. The use of multiple domains allows for a di fference in employed mesh sizes for the macro- and mesoscale. For domains which play a crucial role in the failure process, we apply a mesoscale level meshing, while less critical components can be modelled by a less computationally expensive macroscale mesh. The crack behaviour is modelled by using the GFEM method, while the joint degradation is described using a plasticity based cohesive zone model, with a smooth yield surface. For the purpose of domain decomposition, we propose the use of a FETI method. | Keywords: | computational plasticity, masonry, domain decomposition, FETI, GFEM, cohesive zone | Document URI: | http://hdl.handle.net/1942/12296 | ISBN: | 978-84-899-2573-1 | ISI #: | 000313557900035 | Category: | C1 | Type: | Proceedings Paper |
