Bending Analysis of Asymmetric Functionally Graded Material Sandwich Plates in Thermal Environments

Abstract

This paper investigates the bending of asymmetric functionally graded material (FGM) sandwich plates subjected to thermo-mechanical loads in thermal environments. In this paper, a thermo-mechanical analysis model for asymmetric FGM sandwich plates is proposed, which contains only four control equations and four unknown variables. The governing equation is obtained through refined shear theory and the principle of virtual work, and the Navier method is used to solve it. Numerical examples of simply supported FGM sandwich plates under thermo-mechanical loads are given to verify the accuracy of the model. Finally, detailed studies are conducted on the bending of asymmetric FGM sandwich plates under thermo-mechanical loads, exploring the effects of various parameter changes on their bending behavior, and providing strong guidance for the application of asymmetric FGM sandwich plates in industrial production practice.

Contribution of Various Loads to the Convex Shape of Rock Wool Insulation Slabs during Production

“…Although mechanically and thermally loaded systems Multiple studies on combined temperature and mechanical loading influence on the stress-strain state of steel [4] and other constructions [5] were performed in the past, especially concerning fire safety. Although mechanically and thermally loaded systems have been analytically solved for various complex situations, e.g., [6,7], real-life examples usually become too complex for analytical solving and therefore experimental, in combination with numerical methods, are often used [8]. e.g., Lausova et al [9,10] performed an experiment validated by numerical finite element (FE) simulation of a steel frame structure under fire loading, which caused a non-uniform temperature load over the cross-section and thus additional internal forces.…”
