Abstract
Using finite element (FE) method corrects the microstress field result ing from the theory of homogenization in the region of composite in vi cinity of the boundary. Obtains the corrected microstress field via an unsmearing procedure based on the known global solution and local pet urbation. Analyses two examples: near a free boundary and next to a co nstrained border. FE models are constructed using both commercial FE c ode and the authors' program for homogenization with some interfacing procedures. Shows qualitative results oi computations and estimates in fluence on the microstress description of the local perturbation near the boundary.
