Physico-mathematical modeling and informational technologies| Резюме: | A micromechanical model is developed to determine effective inelastic properties of nanocompositeunder monoharmonic deformation by taking into account detailed micro-structuralgeometries and constitutive models of the constituents. By using the Correspondence Principle inViscoelasticity and the modified Mori-Tanaka method, the effects of interface between inclusionand matrix is taken into account. By applying the presently developed model, a numerical analysisfor determination of complex moduli for polymeric nanocomposite reinforced by nanofiberscomposed from carbon nanotubes (CNTs) is conducted at the isothermal conditions. Analysis ofthe complex moduli dependence on frequency and amplitude of strain intensity is performed.Composites reinforced with both unidirectionally aligned and randomly oriented nanofibers areconsidered. Results demonstrate a weak dependence of loss moduli on the frequency of the loadingwithin the wide range of it. |
