The purpose of this study is to investigate the stress and deformation analysis of rotating discs composed of functionally graded materials and variable geometry. In addition to this, the obtained radial stress, tangential stress and radial displacement values can be modeled by means of support vector regression (SVR).
Radial stress, tangential stress and radial displacement values obtained by material index and geometry index were obtained by finite element method. The stress analysis values obtained were modeled with SVR.
In the case of free-free discs, it was observed that radial stresses decreased with an increase in material index, whereas tangential stresses on inner surface decreased significantly and increased on the outer surface. As the geometry index decreases, the radial stresses on both the inner and outer surfaces decrease. The most successful modeling was observed for radial stress, tangential stress and radial displacement, respectively, although the modeling performed with SVR yielded successful results for each of them.
The modeling of radial stress, tangential stress and radial displacement values obtained by material index and geometry index with SVR represents a research gap that this study aims to address.
