Ударное нагружение ступенчатого стержня из реономного материала
(БНТУ, 2011)Considered is the development in time of stresses and strains in the straight rod of two different cross-sectional areas and a rigid mass (M > 0) at the free end during an impact with an absolute-rigid motionless barrier of infinite weight. Material of the rod is a rheonomic elastic-plastic body described by Maxwell's equation with nonlinear viscosity.2020-05-26 -
Установившаяся ползучесть трёхслойных армированных цилиндрических оболочек с лёгким заполнителем
(БНТУ, 2011)It is carried out the mathematical simulation of creep of the three-layered cylindrical shells, reinforced by the fibers of a constant cross section. It is investigated creep of the shells with the unequal strong and equal strong stressed reinforcement, loaded, in the general case, with transverse pressure and axial forces. Solution of the problem about creep of shells under the ...2020-05-26 -
Цилиндрический изгиб ортотропной трехслойной пластины с нелинейно упругим заполнителем
(БНТУ, 2011)Cylindrical bending of а three-layer orthotropic plate with a nonlinear elastic filler is considered. For the kinematics description of carryings layers accepted the Kirchhojf hypotheses. To describe kinematics of pack of the plate hypotheses of the broken normal are accepted. We obtain the system of equilibrium equations, and applied Ilyushin's experimental-theoretic method to solve it.2020-05-26 -
Численный анализ свободных колебаний цилиндрической конструктивно анизотропной оболочки при различных граничных условиях
(БНТУ, 2011)The analytical solution of approximate natural frequencies for the free vibration of cylindrical shells of GFRP (glass fiber reinforced plastic) with clamped boundary conditions at one end and simple supported boundary conditions at another end is presented using the Rayleigh-Ritz method, while the winding angle varies. Frequency variations for different vibration modes with ...2020-05-26 -
Энергетический метод расчета статически неопределимых систем
(БНТУ, 2011)In article the energy method, which may be successfully used to account of various statically indeterminate systems as “work method”, is considered in details (for examples, the bars, beam and frame). The effectiveness of energy method and the reason of using it in learn process is established.2020-05-26
