Abstract
A low stress seal seals boundaries between rotor sections of a turbofan engine. The low stress seal includes rounded feet on the ends of legs, which rounded feet cooperate with rounded interior corners within a seal groove. The elimination of sharp interior corners reduces stress and prevents the fatigue failures.
