It doesn't matter whether there is hole or not. Imagine that you draw a circle in the place of hole, then change the temperature of the plate, then cut out the hole around the expanded or contracted shape of the line. Since the stress in the plate was zero everywhere before cutting, it will stay zero after cutting, and cutting the hole will not change the shape of the plate.
Mathametical explanation,
If there is no elastic stress in the plate, the strain field is ϵxx=ϵyy=ϵzz=αΔT and the shear strains are all zero, where α is the corefficient of expansion and ΔT the temperature change. Because the strain field is symmetrical in x y and z, this means that ANY two points that were originally a distance d apart become a distance d(1+αΔT) apart, indepedent of the shape of the object, and whether or not it contains holes.
