In-plane stress distribution in a spinning annular disk is studied analytically. The disk is clamped at the inner boundary and subjected to a stationary distributed load along the outer boundary. The solution is determined through a Galilean transformation by using the Lame´ potential functions and the two-dimensional elasticity theory. Numerical results are presented for WA vitrified grinding wheels with outer radii of 50 mm and inner radii of 25 mm rotating at 3000 rpm and 15000 rpm.
