Abstract
Technology for producing hybrid nanocomposite materials with a 7075-T6 aluminum matrix and a filler in the form of nanoparticles is proposed. A review of experimental data and computer and theoretical models of crack initiation is presented. The mechanisms of microcrack initiation under uniaxial tensile load are determined. To study the fracture of loaded nanocrystalline materials and determine their mechanisms, a model is proposed that describes the formation and growth of nanocracks near the tips of elliptical cracks in a hybrid nanocomposite material. The dependences between the applied force and the crack length are obtained using the parameters of a modeled crack.
