摘要：
Using finite element (FE) method corrects the microstress field resulting from the theory of homogenization in the region of composite in vicinity of the boundary. Obtains the corrected microstress field via an unsmearing procedure based on the known global solution and local peturbation. Analyses two examples: near a free boundary and next to a constrained border. FE models are constructed using both commercial FE code and the authors' program for homogenization with some interfacing procedures. Shows qualitative results oi computations and estimates influence on the microstress description of the local perturbation near the boundary.
