“…Similarly, as cited in [5], the analytical model that used the beam theory and plane strain numerical FEM models could be transformed into a more complicated shell or 3D models, and other stochastic or dynamic (e.g., the start-up, steady-state, modal analysis, etc. (see, e.g., [28])) solutions can be used; see, e.g., [15][16][17][18][19][20][21][29][30][31][32][33][34][35]].…”

Experimental and Stochastic Application of an Elastic Foundation in Loose Material Transport via a Sandwich Belt Conveyor—Part 2

et al. 2023

This article serves as a continuation of our previously published work and focuses on loose material transport via sandwich belt conveyors. Experimental, analytical, stochastic, and numerical approaches are used to obtain and utilize the moduli of a bilateral Winkler elastic foundation that represent a loose material, which is wheat (Triticum aestivum) that is free of bran in this case. The solutions were obtained for a uniformly and nonuniformly distributed loose material. The task of the conveyor with loose material is simplified into a symmetric task, i.e., a beam on an elastic bilateral Winkler foundation, for an analytical solution and stochastic solution (Anthill and Matlab sw). In a numerical approach, this is considered a plane strain problem within the finite element method (Ansys and MSC.Marc sw). The experimental data are evaluated and used to obtain the functions of Winkler elastic foundation moduli, which are further considered in the numerical solution. The finite element method mainly serves as a verification tool. The acquired histograms of the elastic foundation moduli can be further applied in various scientific and research fields.

“…Due to the complexity of the whole process, the Finite Element Method (FEM) is used and the problem is solved as a planar one [2][3][4][5]. The Winkler elastic foundation model, which is commonly used in mechanics, is used for the interaction of the Earth's crust and mantle, as shown in Figure 1 [9,[13][14][15][16][17]. However, application of the Winkler elastic foundation in geomechanics is a new way of solving the problem.…”

“…We focused on thermal heating of the crust because it is usually neglected or not considered, but it has a significant influence. Nevertheless, a somewhat simple probabilistic model has been developed which respects the real variability of input and output quantities [9,[15][16][17][18][19][20][21][22][23][24][25].…”

Analysis of the Influence of Thermal Loading on the Behaviour of the Earth’s Crust

2023

The article focuses on the deformation and strain-stress analysis of the Earth’s crust under external thermal loading. More specifically, the influence of cyclic changes in the surface temperature field on the stress and displacement inside the crust over a two-year time span is investigated. The finite element program MSC.Marc Mentat was used to calculate the stresses and displacements. For practical analysis reasons, the Earth’s crust is simplified as a planar, piecewise homogeneous, isotropic model (plane strain), and time-varying temperature functions of illumination (thermal radiation) from the Sun are considered in the local isotropy sections of the model. Interaction between the Earth’s crust and mantle is defined by the Winkler elastic foundation. By applying a probabilistic approach (Monte Carlo Method), a new stochastic model of displacements and stresses and new information on crustal displacements relative to the Earth’s mantle were obtained. The results proved the heating influence of the Sun on the Earth’s crust and plate tectonics.
