SUMMARYStress intensity factors in thin-walled cracked structures are computed using a mixed-dimensional finite element (FE) shell/extended finite element (XFE) 3D formulation. The present approach belongs to the family of 'substructuring' methods. The domain is decomposed into cracked and safe subdomains which are solved by the XFE-code and the FE-software, respectively. The XFE-3D domain may contain cracks that do not necessarily join the top and bottom faces of the plate. The interface problem is solved using the finite element tearing and interconnecting method. Several validations are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
