Abstract: A device and methods are provided for deep rolling. In one embodiment, a deep rolling tool includes a fork having a base section and a plurality of fork arms, wherein each fork arm extends outwardly from the base section and wherein the fork arms are separated from one another to form an opening. The deep rolling tool may also include a plurality of rolling elements configured to apply a compressive stress to articles received by the deep rolling tool, wherein each rolling element is mounted at the distal end of a fork arm, and wherein each rolling element includes a cantilever shaft retained by a fork arm and a crowned roller.
