“…The study highlighted the potential of FGM in mitigating stress singularities along the interfaces. Based on the Fourier series expansion method, Han et al [20] conducted a comprehensive investigation on the buckling behavior of a cylindrical shell coated with FGM under thermal loading conditions. Mao et al [21] simulated the sliding interaction between an FGM-coated half-plane and a homogeneous half-plane to investigate the frictional heat and thermal contact resistance in brake systems.…”

This study aims to provide analytical solutions for circular plates coated or undercoated with functionally graded materials (FGMs) having Young’s modulus functionality through the radius. The circular plates are subjected to thermal loads in radial and thickness directions. Because of the uncoupled stretching–bending problem of the radially FGM circular plate, the bending equilibrium equations in terms of displacements of the FGM-coated or -undercoated circular plates with Young’s modulus based on the power–law function were established individually. General solutions for the homogeneous portion or FGM ring of the radially FGM-coated or -undercoated circular plate were developed separately. Subsequently, analytical thermal solutions for the radially FGM-coated or -undercoated circular plate were evaluated by solving the simultaneous boundary and continuity conditions equations. The analytical results were validated by comparing them with finite element solutions. When degenerated, they coincided with those of the homogeneous circular plate in the literature, enhancing the obtained solutions’ reliability. These analytical solutions provide valuable insights into the plates’ responses and expand the understanding of their mechanical behaviors under thermal loads. Furthermore, the effects of the FGM thickness, the material index, and the thermal loading conditions on the mechanical behaviors were under investigation. This parameter study offers valuable perspectives into the influence of these factors on the plate’s structural response and aids in the optimization and design of FGM-coated or -undercoated circular plates.

“…The study showed that the buckling behaviour of these structures under thermal loading is different from that under mechanical loading, and the buckling load is affected by the material properties and boundary conditions. Han [14] derived the buckling load and critical buckling mode of the cylindrical shell and showed that the buckling load of the cylindrical shell under thermal loads was lower than that under mechanical loads. Kadoli and Ganesan [15] considered a rectangular tube and a cylindrical shell made of aluminium alloy and subjected them to thermal loads and showed that the buckling behaviour of the structures was significantly affected by the thermal load.…”

Buckling analysis of thin-walled structures is essential to ensure their structural integrity under various loading conditions. The study aims to analyse buckling in thin-walled structures, particularly a C-section channel, under different loads, considering cases with and without holes, using FEM. It investigates hole impact on buckling, critical load, and mode shapes, offering insights for C-section channel design. A finite element method (FEM) is used to model the structure and simulate mechanical and thermal loading conditions. Additionally, the study investigates the critical buckling load factor and mode shapes for both cases with and without holes. The results show that the presence of holes significantly affects the buckling behaviour of the structure. The mode shapes indicate that the buckling behaviour of the structure is different for each case. The critical buckling load factor is lower for the C-section channel with holes, indicating a higher risk of buckling. The results of this study provide insights into the buckling behaviour of thin-walled structures and demonstrate the importance of considering the presence of holes in the design and optimization of C-section channels.

“…Using Von-Karman-Donnell theory, thermal buckling (Daikh, 2020) and post-buckling (Hieu and Tung, 2020) studies on FG sandwich cylindrical shell was performed, the analysis reveals the effect of skin thickness and its volume composition, which played a predominant role in increasing the buckling load. The thermal buckling of FG coated cylindrical shell was found to be increased as the coating thickness increases (Han et al , 2017). Al-Furjan et al (2020) performed buckling and post-buckling analysis on a disk by using von Karman’s non-linear plate theory.…”

Purpose The purpose of this study is to investigate Thermo-mechanical limit elastic speed analysis of functionally graded (FG) rotating disks with the temperature-dependent material properties. Three different material models i.e. power law, sigmoid law and exponential law, along with varying disk profiles, namely, uniform thickness, tapered and exponential disk was considered. Design/methodology/approach The methodology adopted was variational principle wherein the solution was obtained by Galerkin’s error minimization principle. The Young’s modulus, coefficient of thermal expansion and yield stress variation were considered temperature-dependent. Findings The study shows a substantial increase in limit speed as disk profiles change from uniform thickness to exponentially varying thickness. At any radius in a disk, the difference in von Mises stress and yield strength shows the remaining stress-bearing capacity of material at that location. Practical implications Rotating disks are irreplaceable components in machinery and are used widely from power transmission assemblies (for example, gas turbine disks in an aircraft) to energy storage devices. During operations, these structures are mainly subjected to a combination of mechanical and thermal loadings. Originality/value The findings of the present study illustrate the best material models and their grading index, desired for the fabrication of uniform, as well as varying FG disks. Finite element analysis has been performed to validate the present study and good agreement between both the methods is seen.
