| Summary: | Calculation technique of the elastic stiffness coefficient of interatomic binding and interatomic forces for the crystal lattice of the deformed body is presented. The base of the investigation is the experimental weight-loading curves made both in the quasi-static regime and in dynamics. Dependence of the interatomic forces was found to be more complex than that, which can be described by the potentials like Morse. Thus, to increase the modeling accuracy of mechanical characteristics it is reasonable to turn to the potentials with larger number of parameters (for example, spline potentials). |
