Constant moment testing device for elongated members |
摘要 |
A testing device applies a load controlled bending moment which is constant along a length of an elongated member. The testing device also includes a drive system which rotates the elongated member while the bending load is applied to rapidly find defects which may only appear at a particular rotational position to determine whether the bending stiffness is uniform about the entire diameter of the elongated member.
