N2 - In this article, we present a novel pixel-based nonlocal discrete computational tool for the modeling and simulation of mechanical behaviors of composite materials with isotropic phases based on their photographic microstructural information. First, formulation of the proposed model is presented and interface modeling is discussed. Following this, a procedure on quantifying materials effective elastic properties is provided. Details on a spring-based failure criterion for modeling of fracture events are discussed. After that, investigations on effects of material microstructure, interface properties and inclusion characteristics on effective elastic and fracture properties of bi-phase composites reinforced by various inclusions are performed. Based on current study, conclusions are drawn at the end.
