In this paper, the bicubic splines in product form are used to construct the multifield functions for bending moments, twisting moment and transverse displacement of the plate on elastic foundation.
Beams, plates and shells on elastic foundations
The vibration and stability analysis of uniform beams supported on two-parameter elastic foundation are performed. The second foundation parameter is a function of the total rotation of the beam. The effects of axial force, foundation stiffness parameters, transverse shear deformation and rotatory inertia are incorporated into the accurate vibration analysis. The work shows very important question of relationships between the parameters describing the beam vibration, the compressive force and the foundation parameters. For the free supported beam, the exact formulas for the natural vibration frequencies, the critical forces and the formula defining the relationship between the vibration frequency and the compressive forces are derived. For other conditions of the beam support conditional equations were received.

Show all documents Table 3 and Table 4 present the influence of the elastic foundation on the natural frequency of the plate. From those two tables, the frequency of plate increases significantly when the stiffness of the elastic foundation increases. Figures 4 and 5 show the influence of the foundation on the dynamic response of penta-graphene plates. A Solution for Orthotropic Rectangular Thin Plate on Elastic Foundation with Horizontal Resistance Based On a Modified Function In the current research, the orthotropy of the plate and the horizontal friction between the foundation soil and the foundation plate are rarely considered simultaneously. Besides, it is difficult to construct a solution that satisfies not only the governing differential equation of plate bending, but also the boundary conditions on four free edges and the conditions at four free corner points.

Zenkour, M. This paper deals with the static response of simply supported functionally graded material FGM viscoelastic sandwich plates subjected to transverse uniform loads. The FG sandwich plates are considered to be resting on Pasternak's elastic foundations. The sandwich plate is assumed to consist of a fully elastic core sandwiched by elastic-viscoelastic FGM layers.
The influence of soil heterogeneity is studied on the bending of circular thin plates using two modified Vlasov foundation models. The model parameters are determined reasonably using an iterative technique. According to the principle of minimum potential energy and considering transversely isotropic soils and Gibson soils, the governing differential equations and boundary conditions for circular thin plates on two modified Vlasov foundations are derived using a variational approach, respectively. The determination of attenuation parameters is a difficult problem, which has hindered the further application of the Vlasov foundation model. The equation that must be satisfied by the attenuation parameter is determined, and an iterative method is used to solve the problem.

Стратмор и Сьюзан отволокли его туда через шифровалку и связали ему руки и ноги толстым кабелем от одного из лазерных принтеров. Сьюзан до сих пор была ошеломлена ловкими действиями коммандера.
