4. Conclusions

Summarizing the obtained results, we can conclude that the proposed multiscale model based on MCA method allows simulating and studying the deformation and fracture of the ceramic composites with elongated soft inclusions. The simulations of five specimens with the unique position of individual inclusions for each value of its volume fraction show that there is no scattering of elastic modulus values while the scatter of strength and Poisson’s ratio values is significant. Random orientation of elongated soft inclusions results in higher strength value and does not change Young’s modulus of the model ceramic composite. The magnitudes of Poisson’s ratio along both lateral directions are approximately the same and keep constant value for all range of volume fraction of elongated soft inclusions taking into account a large scatter of these parameters values.
