Равнительный численный анализ механического поведения нанотрубки в случае применения разных механических моделей
Нагорный, Ю. Е.; Репченков, В. И.; Чижик, С. А. (БНТУ, 2008)It was developed computer model of single-walled carbon nanotube on basis of valence-force-field approach. One performed computational experiments to determine mechanical characteristics (linear elasticity modulus, crosscut compression coefficient, shear modulus) according nanotube dimensions. One realized comparison present results with results obtained within Urey-Bradley model. ...2019-11-15 -
Численное моделирование механического поведения наноструктуры графена, содержащей разрез
Нагорный, Ю. Е.; Репченков, В. И.; Чижик, С. А. (БНТУ, 2008)The mathematical model of graphen nanostructure containing a cut is constructed and realized in package Mathematica. Dependences of forces arising in valence bonds at loading and Young modulus from length of defect are investigated. It is shown, that at edge of a cut forces grow in some times. Young modulus decreases almost in two.2019-11-15
