Abstract
A transition portion adjacent the uncored section at a trailing edge of a cored turbine bucket displaces some of the regions of maximum stress concentration so that the maxima do not superpose and produce radial cracking at the junction of the uncored section with the walls of the cored portion. The transition section includes a curved portion joining a ramp leading to the tip.
