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 ...

The axisymmetric forced vibrations of a viscoelastic circular sandwich plate on an elastic foundation are studied. The plate is subjected to axisymmetric loads with frequency equal to one of the natural frequencies of the plate. The foundation reaction is described by the Winkler model. The problem on the viscoelastic plate oscillations was solved by averaging. The numerical ...

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.

Sandwich thin walled beam open cross section is considered. For the kinematics description carryings layers accepted the hypotheses Broken Normal. Filler is hard. Boundary problem come to the linear system of differential equations with variable coefficients. Received combined equations of equilibrium and its analytical solution via moving.

Рассматривается задача о давлении плоского штампа на ортотропное идеально пластическое полупространство. Зависимость напряжения текучести от направления главного напряжения задается эллипсоидом анизотропии. Угловая точка штампа и прямолинейная граница полупространства порождают центрированный веер прямолинейных характеристик, как и в случае изотропного тела, с аналогичной кинематикой ...

The problem of act of normal loading on transversely isotropic half-space consisted from horizontal layers in is solved. The layers are unbounded. Problem is solved in 3D. The method of solution is based on using of Fourier transform. The cubature formulae are obtained for the following types of problem: resting of elastic layer on inflexible and elastic half-space, resting of ...

The approach permitting modeling the work of a human joint as interacting surfaces with allowance of the change of physical-mechanical properties and damage accumulation in tissues, participating in motion in a joint is offered. The obtained results demonstrate changes going on in a site of a contact during ageing process.

Difficult movement of an elliptic pendulum is considered. Are made and solved the differential equations describing movements of a slider and a ball. In work it is accepted, that during the initial moment an angle of rotation of an arrow of a pendulum from a vertical and speed of a slider are equal to zero, angle speed of rotation of an arrow are not equal to zero. With the account ...

Biomechanical model of the reconstructed middle ear subjected to tympanostapedoplasty and the stapes footplate perforation is proposed. The basic goal of this study is to clear up the influence of the tangential displacements in an eardrum at modes andfundamental frequencies of the reconstructed middle ear. The reconstructed tympanic membrane is modeled as an isotropic elastic ...
