Abstract: The longitudinal compression strength of single-directional fiber-reinforced composite is related to many factors, such as the mechanical properties, the fractions of components, and the distribution of flaws. There are no abroad and uniform opinions about its longitudinal compressing break mechanism yet. Thus, a review of recent developments in the compression strength mesomechanical forecasting models of single-directional fiber-reinforced composites is presented. The damage mechanisms based by these models and the affecting factors considered in them are analyzed. The application conditions of each models are shown, and the model choosing method of combining experiment and theoretical analyze is suggested.

Abstract: Modelling of polycrystalline ceramics built up of different phases has been done within mesomechanical approach. Porous ceramics consists of matrix material and second phase – pores. Such material has non-linear and complex overall response to applied load. Modelling of porous polycrystalline material was performed by multiscale approach describing different phenomena occuring at different scales: micro- meso- and macro- with application of averaging procedure over the Representative Surface Element (RSE).
