1. A dome-deflector assembly for a combustor of a gas turbine, the dome-deflector assembly comprising:
a dome portion having a dome-side swirler opening therethrough; and
a deflector portion having a deflector-side swirler opening therethrough and extending about a deflector-side swirler opening centerline axis, the dome portion and the deflector portion being connected together to form a dome-deflector cavity therebetween,
wherein the deflector portion extends from a first-side surface to a second-side surface, the second-side surface being arranged within the dome-deflector cavity, and a plurality of stress-relief contours extending within the second-side surface forming a plurality of circumferential grooves extending circumferentially about the deflector-side swirler opening centerline axis and arranged in a pattern about the deflector-side swirler opening.
