Opis:
In the paper, theoretical knowledge about base solution of common differential equations with variable parameters is presented. The solutions are applied to mechanical problems of discrete, distributed and discrete-distributed homogeneous elastic models of structures and structural components. In this paper, the influence function and its properties are presented. The influence function is applied to analysis of the bending curve of a beam with constants and variable parameters. The presented method of the influence function is based on the mathematical similarity of differential equations describing free vibrations and deflection of beams, which are fourth-order equations with variable coefficients. In this paper, examples of calculation of support reactions as function of stiffness of the beam and elastic supports are presented.

Opis:
The paper concerns the problem of the influence of thermal actions on the structural behavior of sandwich panels with unspecified elastic supports. An ordinary sandwich panel theory is used. The boundary conditions have the arbitrary form of elastic supports. The solution of a statically undetermined system with limitations of horizontal displacement and rotation is derived. The illustrative examples are presented and the problem solution is discussed.

Opis:
The paper examines the problem of the influence of restrictions on freedom of horizontal displacements in thermally loaded sandwich beams. The classical theory of sandwich beams and panels with thin facings and a soft core has been applied. It was assumed that the cross-section of the beam could be asymmetric geometrically and materially. The beam has vertical supports and additional horizontal supports limiting the freedom of horizontal displacements. The supports are linearly elastic and the rigidity of the upper and lower support can be arbitrary. The static problem of single-span beam with support conditions identical at both ends of the beam was solved in the paper. Each of the sandwich facings has been subjected to temperature change. The derived formulas were used in the example illustrating the importance of the problem.

Opis:
The paper analyses the influence of the stiffness of the elastic support of the stepped column on the natural vibration frequency and the critical load values. The exact stability analysis and dynamic analysis using a continuous mass distribution were carried out. The safe areas and the natural frequency for different column support conditions were determined.

Opis:
Free vibration analysis of homogeneous and isotropic thin circular and annular plates with discrete elements such as elastic ring supports is considered. The general form of quasi- -Green’s function for thin circular and annular plates is obtained. The nonlinear characteristic equations are defined for thin circular and annular plates with different boundary conditions and different combinations of the core and support radius. The continuity conditions at the ring supports are omitted based on the properties of Green’s function. The fundamental frequency of axisymmetric vibration has been calculated using the Newton-Raphson method and calculation software. The obtained results are compared with selected results presented in literature. The exact frequencies of vibration presented in a non-dimensional form can serve as benchmark values for researchers to validate their numerical methods when applied for uniform thin circular and annular plate problems.
