dcterms:description
The present paper describes a two-step homogenization for the evaluation of effective elastic properties of textile reinforced ceramic composites. Attention is devoted to polysiloxane matrix based composites reinforced by plain weave textile fabrics. Basalt and carbon reinforcements are considered. X-ray microtomography as well as standard image analysis is utilized to estimate the volume fraction, shape and distribution of major porosity which considerably influences the resulting macroscopic response. The numerical procedure effectively combines the Mori-Tanaka averaging scheme and finite element simulation carried out on a suitable statistically equivalent periodic unit cell. The 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 CT projections together with experimental data derived from measurements of phase velocities of ultrasonic waves is also provided.
