Title of the articleNumerical modeling of stress-strain state of hybrid composites
Abstract.One of the ways to introduce hybrid (with heterofiber filling) polymer composite materials of structural purpose into the construction practice is to improve their numerical modeling of the stress-strain state at various stages of development, which allows performing a preliminary assessment of optimal options at an early stage. The purpose of the study is to determine the ultimate load that the composite will withstand in bending, tension and compression, to assess the influence of the content of different phases with recommendations for the assignment of geometric parameters and mechanical characteristics of the composite. The objectives of the research are performance of strength calculations in tension, compression, bending of hybrid beams, comparative analysis of different reinforcement on strength and stiffness parameters, preliminary evaluation of the optimal variant of reinforcement of hybrid composite. Results. Numerical modeling of stress-strain state of hybrid polymer composite materials, namely, tensile, compression and bending calculations have been carried out. Comparative analysis of different reinforcement on strength and stiffness parameters has been carried out. The method of preliminary estimation of the optimal variant of reinforcement of hybrid polymer composite material has been analytically developed. Conclusions. The significance of the obtained results in the construction industry lies in the fact that numerical modeling of the stress-strain state of hybrid polymer composite materials allows expanding the field of their application, the model is recommended to be used in solving scientific and engineering problems.
