Устойчивость тонких гофрированных оболочек, лежащих на упругом основании, под действием неоднородного гидростатического давления
(БНТУ, 2008)The problem of stability of the thin-walled corrugated shell laying on the elastic foundation under action of non- uniform pressure is considered. The influence of the elastic foundation is taken into account as the additional pressure within the framework of Winkler's model. The rigid clamped conditions are considered at the edges of the shell. The obtained resolving equation ...2019-11-15 -
Устранение плеоназмов в операторном методе решения первой основной динамической задачи теории упругости
(БНТУ, 2008)The general solution that contains two arbitrary functions of longitudinal coordinates and time has been constructed for the elastic isotropic area comprising two parallel planes. The equilibrium equations within the area and homogeneous shearing stresses on the planes z-±h are accomplished identically.2019-11-15 -
Численное моделирование механического поведения наноструктуры графена, содержащей разрез
(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
