“…Works [4,5] study the bending of elastic isotropic isosceles triangular plates with the following boundary conditions: hinged or rigid edges; they were calculated using the finite element method with the use of approximating functions. As an example, a calculation is given for the bending of a plate in the form of a right-angled triangle with hinged support along the contour.…”

In this paper, there are studied the dynamic processes (free and forced oscillations) of isotropic cantilever plates in the form of an isosceles (wedge-shaped) triangle. In the study, the finite difference method has been applied using a regular one-dimensional (linear) grid. The finitedifference equations developed by the authors for point-distributed masses along the length of the wedge are presented, taking into account the linearly variable bending stiffness. On this basis, the results of studies in the form of amplitude-frequency characteristics (frequencies, dynamic forces and deflections) in the resonant and near-resonant regions have been obtained. The content of theoretical provisions and applied results can be widely used in the scientific and engineering fields and in the field of mechanics of structures.

“…In [4,5], the bending of elastic isotropic plates in the form of isosceles triangles with different boundary conditions (hinged or rigid edges) is considered. For their calculation, the finite element method with the construction of approximating functions was used, and an example was also given for calculating the bending of a plate in the form of a right-angled triangle with hinged support along the contour.…”

In this paper, the bending of cantilever triangular plates at the same angles of inclination of the side edges to the base is investigated. Due to the complexity of the boundary conditions, a numerical finite difference method is applied using a grid of scalene triangles that fits well into the contour of the plate. To solve the problem of an acute angle at the top of the plate, the method of combining the results of calculating a cantilever bar of variable bending stiffness with similar results of calculating a triangular plate supported along the contour using a reduction factor is applied. The results of deflections of the cantilever triangular plate at different angles of inclination of the side edges to the base are given. The theoretical provisions and applied results of this study can be used both in scientific research and in engineering design.

“…Over the last years in structural mechanics, the isoperimetric method of two-dimensional problems solution develops rapidly. Its geometric ground is based on isoperimetric properties of so-called form factor [8][9][10][11][12][13][14][15][16][17]. According to the carried out investigations, geometrical rigidity of sections with arbitrary convex contour functionally depends on this factor.…”

The article considers the problem on a pure torsion of elastic prismatic beam with arbitrary convex contour in the isoperimetric form. It is proved that for isometric sections with a convex contour, the normalized geometrical torsion rigidity depends on one parameter only-the form factor. The sections in the form of isosceles and rectangular triangles, rectangles, and parallelograms are considered. Graphical comparison of the given geometrical rigidity of the examined sections with the value reciprocal of the form factor displayed the real similarity of these graphs. Analysis of these graphs provides the conclusion that all the range of values of the normalized geometrical rigidity of parallelogram sections is limited from above with values i k for rectangular sections, and from below-for the rhombic sections. Applying the method of geometrical modeling rigidity of the sections by a section form, we suggest the interpolation method to determine the given geometrical rigidity of the sections by the form factor. The obtained results are otherwise satisfactory when performing engineering calculations.
