Abstract

Thermal buckling is a common failure mode for plate structures, and its analysis is crucial for ensuring the safety and reliability of aircraft structures. In this study, the thermal buckling of isotropic plate structures under a uniform temperature distribution is investigated by using the generalized differential quadrature method. The method is implemented to investigate the effect of temperature change on the stability of isotropic plate structures. The proposed method is validated by comparing the results with those obtained using commercial analysis tools, and analytical solutions for different boundary conditions, alloys commonly used in the aerospace industry, plate thickness and aspect ratio. The results show that the employed method is a promising approach and an effective tool for analyzing the thermal buckling of isotropic plate structures under uniform temperature distribution and can be used to optimize the design of aerospace structures and other structures that are subject to temperature changes. The method can also be used to investigate other buckling-related problems, such as stability analysis and vibration analysis.
