Parameter-Based Finite Element Modeling of Functionally Graded Rotating Disks Subject to Thermal Loadings

A parametric-based finite element model was developed to analyze the behavior of rotating disks made from functionally graded materials (FGMs) subjected to thermal loads. The model enabled the rapid determination of critical speeds to prevent slip and plastic deformation, while also enabling the analysis of disk performance under varying operational conditions, such as different rotational speeds, disk diameters, and material gradients. The model is a highly efficient tool for design engineers to assess stress and deformation in rotating disks and facilitates the optimization of FGM parameters, offering valuable support to FGM designers.
