Abstract
With the usual assumptions of a plane stress state (σ z = 0) made for rotating disks, the stress field is generally biaxial. Uniaxial stress conditions can only occur locally: at the inner edge of non-rotating disks loaded at the outer edge (Figs. 2.1 and 2.2) and of only rotating disks (Fig. 2.6), and at the outer edge of non-rotating disks loaded at the inner edge (Figs. 2.3 and 2.4), of rotating annular disks (Fig. 2.6) and rotating solid disks (Fig. 2.15). Biaxial tensile, tensile-compressive and tensile or compressive stress occur respectively at the centre of only rotating disks (Fig. 2.15), at the inner edge of non-rotating annular disks loaded at the inner edge (Figs. 2.3 and 2.4) and at the outer edge of non-rotating annular disks loaded at the outer edge (Figs. 2.1 and 2.2). Biaxial tensile, compressive or tensile-compressive stress conditions occur in the intermediate sections of the disk.
