An Improved System for the Nondestructive Evaluation of Steel
A non-magnetic horizontal load frame has been constructed allowing for x-y motion and rotation about the specimen axis in order to investigate the state of stress in steel components with a SQUID gradiometer. Tensile and cyclic loading can be performed under load or strain control. Data are taken by a Masscomp data acquisition system. Initial tests of this system have been made using a vertically-mounted SQUID gradiometer.
