Claim:
1. A deep rolling tool for applying compressive stress, the deep rolling tool comprising: a flexible first fork arm and a flexible second fork arm each extending outwardly from a base section, wherein the flexible first fork arm and the flexible second fork arm are separated from one another to form an opening; a first rolling element rotatably secured to a distal end of the flexible first fork arm; a second rolling element rotatably secured to a distal end of the flexible second fork arm; wherein the flexible first fork arm and the flexible second fork arm are configured to locate the first rolling element and the second rolling element in a facing spaced relationship with respect to each other and wherein the flexible first fork arm and wherein the flexible second fork arm extend outwardly from the base section without a pivot such that movement of the distal end of the flexible first fork arm with respect to the distal end of the flexible second fork arm is dependent upon a flexural stiffness of the flexible first fork arm and a flexural stiffness of the flexible second fork arm; and wherein the first rolling element and the second rolling element are configured to apply a compressive stress to an article received in the opening.
