“…In modern structures of thin-sheet shells, the multilayer shells became widespread, in which a high load-bearing capacity is achieved with a minimum loss of metal due to a rational distribution of it in the separate elements of a structure [1][2][3][4][5]. These structures with a relatively small mass have high strength and rigidity characteristics, good sound and thermal insulation properties [6][7][8][9].…”

The aim of the work is a comparative analysis of structural features and mechanical characteristics of spot welded joints of thin-sheet stainless steels 03Х11Н10М2T and 12Х18Н10Т, produced by laser welding in different welding positions. The change in the welding position from vertical to flat allowed extend the ranges of variation of welding modes from about ±5% to about ±10%, at which it is possible to produce a welded joint with satisfactory shape and mechanical characteristics. Higher strength is typical for welded joints obtained in a flat position. It also concerns the maximum value of the shear stress, which for the flat position is higher by approximately 10%, and the average value, which is higher by approximately 24%. In addition, the results of mechanical shear tests of these joints have a significantly lower dispersion.

In this paper for the first time, active vibration control of rotating laminated composite cylindrical shells embedded with magnetostrictive layers as actuators by means of first-order shear deformation theory is studied. Vibration equations of the rotating shell are extracted using Hamilton principle considering the effects of initial hoop tension, Coriolis, and centrifugal forces. The vibration differential equations are reduced to algebraic ones through Galerkin method. The validity of the study is proved by the comparison of some results with the literature results. Eventually, the influence of several parameters on damping characteristics and vibration responses are investigated in detail.

“…In particular, numerous studies have been conducted on the buckling and vibration analysis of FG cylindrical shells. 15–18,21–34 However, studies on the nonlinear forced vibrations 35–41 and dynamic stability of FGM shells are limited. The works are mostly focused on linear and nonlinear free vibration analyses.…”

In the recent years, functionally gradient materials (FGMs) have gained considerable attention with possible applications in several engineering fields, especially in a high-temperature or hazardous environment. In this work, the nonlinear vibrations of a simply supported fluid-filled functionally graded cylindrical shell subjected to a lateral time-dependent load and axial static preload are analyzed. To model the shell, the Donnell nonlinear shell theory is used. The fluid is assumed to be incompressible, nonviscous, and irrotational. A new function to describe the variation in the volume fraction of the constituent material through the shell thickness is proposed, extending the concept of sandwich structures to a functionally graded material. Material properties are graded along the shell thickness according to the proposed volume fraction power law distribution. A consistent reduced order model derived from a perturbation technique is used to describe the displacements of the shell and, the Galerkin method is applied to derive a set of coupled nonlinear ordinary differential equations of motion. Results show the influence of the variation of the two constituent materials along the shell thickness, internal fluid, static preload, and shell geometry on the natural frequencies, nonlinear frequencyamplitude relation, resonance curves, and bifurcation scenario of the FG cylindrical shell.
