NDT testing for 1" diameter smooth bent bar
(OP)
Could anyone make a suggestion on what kind of NDT testing can be performed on 1" diameter smooth bent bar. The purpose is to detect any stress crack at the bent due to the tight bent radius. These bars have been installed to the concrete as the ladder rungs. Thanks.

or more simple ... LPI
depends on what length of crack you want to detect.
maybe even Xray

Now, a hollow bar will deform in as it bends, and tend to compress (crumple) the OD and kink the ID. But a smooth bar (for rebar ??) will not likely show problems on the inside of the bend.

Yes, I know. That's a double negative.

Magnetic particle inspection would be the second choice. More expensive, more equipment, more operator training....but fast results!
Eddy current would be next, but has the same issues as MPI.
