Abstract:

This paper presents a formulation to evaluate the homogenized properties of unidirectional composite laminates based on boundary element method for multiscale analysis. The micromechanical approach (local scale) assumes a Representative Volume Element (RVE) composed by a transversely isotropic ber within of an isotropic matrix, having the your orientation according to orientation of bers in the composite laminate (global scale). The multi- domain Boundary Element Method (BEM) formulation is applied to the RVE elastic problem in conjunction with the mean elds theory in order to evaluate the e ective properties of the laminate. Numerical examples are presented and the homogenized constitutive properties are compared with the respective properties of composite laminate, found in the literature.
