"The present paper describes a two-step homogenization for the evaluation of effective elastic properties of textile reinforced composites. Attention is devoted to carbon and polysiloxane matrix based composites reinforced by plain weave textile fabrics. X-ray microtomography as well as standard image analysis are adopted to estimate the volume fraction, shape and distribution of major porosity, considerably influencing the resulting macroscopic response. Numerical procedure effectively combines the Mori-Tanaka averaging scheme and finite element simulation carried out on a suitable statistically equivalent periodic unit cell. Computational strategy employs the popular extended finite element method to avoid difficulties associated with meshing relatively complex geometries on the meso-scale. Comparison with the results obtained directly from the finite element simulations of available Micro-CT scans is also provided."@en . "RIV/68407700:21110/12:00194171!RIV13-GA0-21110___" .
