“…Research plays a crucial role in advancing our understanding of complex phenomena and developing innovative solutions to real-world problems. In the field of engineering, research is particularly important for designing and optimizing structures that can withstand various types of loads and environmental conditions [14]. One area of research that is gaining increasing attention is the buckling behavior analysis of sandwich cylindrical micro shells with functionally graded porous cores subjected to uniform magnetoelectric fields with thickness stretching.…”

This study examines the buckling behavior of sandwich cylindrical microshells made of functionally graded materials under uniform magneto-electric load. The analysis utilizes a high-order shear and normal deformation shell theory, incorporating a material length scale parameter from the couple stress theory. Hamilton's principle is used to derive the equations of motion and boundary conditions at both ends. The Navier procedure is employed to determine the dimensionless critical buckling load for three types of functionally graded sandwich cylindrical microshells, with a vector used to represent the uniform magneto-electric fields at both ends. Results indicate that angled functionally graded sandwich cylindrical microshells exhibit higher stiffness in couple stress theory than in normal FGS, resulting in an increased dimensionless critical buckling load. Moreover, the material length scale parameter has a significant impact on the dimensionless critical buckling load across various axial and circumferential wavenumbers. An increase in power-law index n for specific values of dimensionless length scale parameter (l/h) leads to a decrease in DCB load according to MCST.

“…They have achieved the control on stability, amplitude and frequency-response behavior. Wankhade and Bajoria (2017) studied the optimization phenomenon of beams with piezoelements which were subjected to the static and dynamic excitations. Scientists have found the optimal location of a piezoelectric patch for the chosen boundary condition of the system.…”

The studies on vibration frequency as well as loading capacity of slender systems are very important issues in the design process. Integration of smart materials with the host structures allows one to create constructions which are able to adjust to the different conditions. The piezo material belongs to the smart materials group. Application of voltage to the piezoparts leads to induction of forces which can cause prestressing of the host structure. The prestressing with the use of piezoceramic elements is a main subject of this paper. The investigated system constitutes a column which is loaded with the specific load. The specific load is realized by means of specially designed heads what results in divergence or divergence-pseudoflutter type of characteristic curves. The results presented in this paper are concern on comparison of the loading capacity magnitude and vibration frequency of a slender system with and without prestressing. Finally, it will be stated when to use complex system with piezopart or the simplified one without it.

The present work exhibits the analysis of a plate with and without cutout considering the dynamic analysis in a transient zone with its application in the civil, structural, and aerospace industry. For this, first-order shear deformable C 0 continuous Finite Element (FE) is implemented to examine transient response of plate. The governing ODE of motion's is integrated using central difference explicit time integration scheme. A lumped mass matrix is obtained by a special diagonlization scheme and the total mass of the element is conserved by inducing effective rotary inertia terms. A FE program is developed based on derived FE formulation to investigate the effect of dynamic loading on such plates. The analysis exhibits the results in terms of displacement, forces, and bending moment of the plate for various aspect ratios and different parameters. The results are shown in terms of tables and graphs for smaller to larger cutout in plates with its different aspect ratio considering transient analysis. The results reveal that transient dynamics analysis shows a considerable difference in the behavior of plates with and without cutout in terms of time period, amplitude, and bending moment than that obtained from static analysis.
