摘要
A cutting element for an earth-boring tool includes a substrate and a polycrystalline, superabrasive material secured to an end of the substrate. The polycrystalline, superabrasive material includes a first transition surface extending from an outer peripheral edge of the polycrystalline, superabrasive material and in a first direction oblique to a center longitudinal axis of the substrate and a curved, stress-reduction feature located on at least the first transition surface. Additionally, the stress-reduction feature may include an undulating edge formed in at least the first transition surface and a waveform extending from the undulating edge formed in at least the first transition surface toward the center longitudinal axis of the cutting element.
