Abstract Scope Particles reinforced composites are widely used for the industrial applications. In present paper the effect of inclusions with irregular shapes on the elastic material properties of two-phase composites is studied. For this, the influence of the surface structure of the inclusion on the elastic properties needs to be determined, in this work by using the FE-Method [1] and an analytical approximation [2]. The irregular shapes of the real inclusions were approximated using smooth three-dimensional structures using methods of the computer algebra and were used for the following FE studies. The representative volume elements (RVE) with typical inclusions with irregular shapes were determined and used for calculation of the effective material properties. Results of the provided studies were compared with experimental results.
