Ring testing machines which embody an annular frame, a ring of jacks, and tension members extending in from the jacks to a ring to be tested. The tension members may be coupled to shoes to fit the inside of the ring to be tested or the ring may be clamped so that the jacks exert a delaminating or separating pull on the radially outer portion of the ring. Heat may be applied to the ring during the testing.
