- Abstract
Non-linear homogenization techniques based on the use of the finite element method are tested, in this paper, for the study of heterogeneous materials. The practical steps of a computational homogenization approach and representative examples related to masonry structures and ceramic materials are presented. The non-linear representative volume elements (RVE) of a masonry structure, including parts with elastoplastic material behaviour (mortar), and a ceramic material with a unilateral contact interface (crack), are created and solved. Parametric analysis has been chosen and used for the description of the strain loading. The average stress and strain in the RVE domain are then calculated. In addition, the stiffness is estimated for each loading level. Finally, two databases for the stiffness and the stress are created, a metamodel based on MATLAB interpolation is used, and an overall non-linear homogenization procedure, is considered. The satisfactory results obtained from the comparison between direct heterogeneous macroscopic models created by commercial software show that the proposed method can be used for the simulation of non-linear heterogeneous structures.
