Description
Summary:This paper presents the microstructure of composite material, which consists of metal inclusions and polyamide matrix, the data of which were obtained by computer modeling. The investigated composite material is one of the main directions in the production of materials for advanced MIM technologies, which allows to refuse expensive injection molding process and use technological processes of layer-by-layer growing of parts. The simulations were carried out in top level programs like DIGIMAT and NASTRAN/PATRAN. The simulation modeling of composites at the micro level made it possible to establish the relationship between the percentage of inclusions and the upper yield strength of the material and the constituent components of the stiffness matrices. All these can be considered as input data for the study of composite material at the macro level. At the macro level, virtual studies of standard specimens printed from polymer yarns were carried out to determine the strength. The simulations were conducted as layer-by-layer staging experiments, here each printed layer was considered as a layer of composite.
