Non-intrusive global-local analysis of heterogeneous structures based on a second-order interface coupling [link]Paper  doi  abstract   bibtex   
In Wangermez et al. (Comput Methods Appl Mech Eng 365:113032, 2020) a second-order coupling strategy of a macroscopic description of a structure and an heterogeneous lower scale description of some local details was proposed. As such, the proposed coupling technique is quite elaborate and not suited for an implementation in a legacy code. The purpose of this paper is to facilitate its implementation by means of a dedicated non-intrusive technique. This leads to several implementation propositions, including the use of MPC conditions, which are available in most of the finite element solver. Its interest is that it does not require any modification of the numerical models and can be implemented with any finite element simulation software. The proposed method has been implemented in the finite element Software Z-set™ used by Safran and is illustrated on an example of a 3D woven composite plate in which a severe weaving defect is introduced.
