\b[No, for a uniform or otherwise axisymmetric disc in steady rotation.] Although individual material elements accelerate, the <mass density> and <mass current> at every spatial point remain constant, and the <mass quadrupole moment> is time independent. There is no <gravitational radiation>. Axisymmetry of the material distribution is necessary for this conclusion: the source does not explicitly specify the disc's density. A counterexample to an unconditional answer is a disc with two equal dense spots at opposite radii; their rotating <mass quadrupole moment> produces <gravitational waves> at twice the rotation <angular frequency>.
