A combustion case for a gas turbine engine. A typical combustion case is generally cylindrical or conical. Apertures penetrate the case, from the outer surface, through the case, to the inner surface. The apertures act as concentration points for stress. To dissipate the stress, bosses buttress the apertures, with each aperture having two bosses: one on the outer surface of the case, and another on the inner surface of the case. The invention eliminates the latter bosses. The invention dissipates stress by providing an array of T-slots on the inner surface.
