Engineers use computational techniques and mathematical models to solve mechanical issues. Beam structure is a fundamental model used in computational mechanics. Today, functionally graded materials have become the most popular and essential materials for the mechanical computations of beams. Functionally graded materials are commonly defined as a special kind of composite in which the material properties vary smoothly and continuously from one surface to another. However, there has been little research on the static bending response of rotating two-layer FGM beams with shear connectors resting on elastic foundations. 

Researchers sought to fill this knowledge gap with a focus on the influence of evenly distributed static loads on the top surface of a beam. In “Finite-Element Modeling for Static Bending Analysis of Rotating Two-Layer FGM Beams with Shear Connectors Resting on Imperfect Elastic Foundations” in the Journal of Aerospace Engineering, authors Le Minh Thai, Doan Trac Luat, Tran Van Ke, and Minh Phung Van used a complex structure with two-layer functionally graded layers connected by shear connectors. To capture the effects of geometric and material properties on the static bending behaviors of the structure, the authors performed many parameter studies which are described in this paper.

The static bending of rotating two-layer functionally graded material (FGM) beams with shear connectors resting on imperfect elastic foundations was performed for the first time in this study. Timoshenko beam theory and the finite-element method are used to derive finite-element formulations. The precision of the current approach and mechanical model is shown by comparing the calculated findings of this study to those of previous precise papers. A wide variety of parameter studies are carried out to capture the impact of geometric and material characteristics on the structure’s static bending behaviors, such as the distance d, rotational speed, volume fraction index, elastic foundation parameters, and boundary conditions. This paper’s theory and mechanical models are fascinating since mechanical systems involving rotational motion are pretty standard in engineering practice. Therefore, the computed results of this work aim to contribute to our understanding of structures of this kind.
