This paper presents a new numerical method for multiscale modeling of composite materials. The new numerical model, called DECM, consists in a DEM (Discrete Element Method) approach of the Cell Method (CM) and combines the main features of both the DEM and the CM. In particular, it offers the same degree of detail as the CM, on the microscale, and manages the discrete elements individually such as the DEM—allowing finite displacements and rotations—on the macroscale. Moreover, the DECM is able to activate crack propagation until complete detachment and automatically recognizes new contacts. Unlike other DEM approaches for modeling failure mechanisms in continuous media, the DECM does not require prior knowledge of the failure position. Furthermore, the DECM solves the problems in the space domain directly. Therefore, it does not require any dynamic relaxation techniques to obtain the static solution. For the sake of example, the paper shows the results offered by the DECM for axial and shear loading of a composite two-dimensional domain with periodic round inclusions. The paper also offers some insights into how the inclusions modify the stress field in composite continua.

The analysis of existing methods for imparting a porous structure to structural composite materials is carried out. In particular, the introduction and subsequent removal of the filler, the addition of foaming agents or separately prepared foam to the suspension, as well as gas formation. Discloses a method of introducing into the material of the hollow microspheres, which finds use in the development of thermal barrier composites. The introduction and subsequent carbonization of additives is considered. A method for producing highly porous carbon-graphite materials with a uniformly distributed pore structure using isostatic pressing with pyrocarbon in the form of a binder is considered. Describes the receipt as highly porous carbon materials of foam coke based on carbon microspheres, carbon materials based on fibers, pressed carbon black, porous pyrocarbon and related materials, as well as porous glassy carbon.

In this paper, the anticipated challenges and future applications of self-healing composite materials are outlined. The progress made, from the classical literature to the most recent approaches, is summarized as follows: general history of current self-healing engineering materials, self-healing of structural composite materials, and self-healing under extreme conditions. Finally, the next stage of research on self-healing composites is discussed.
