Abstract
Standards for non-destructive testing methodologies and methods of fabricating the standards are disclosed herein. The standards include a void-defect coupon that includes a spheroidal void and an elongated void. The spheroidal void has a maximum dimension and a spheroidal void volume. The elongated void had a longitudinal dimension, a maximum transverse dimension, and an elongated void volume. The longitudinal dimension of the elongated void is greater than the maximum dimension of the spheroidal void. The maximum transverse dimension of the elongated void is less than the maximum dimension of the spheroidal void. The methods include forming a first void-defect coupon and forming a second void-defect coupon.
Claims20
A standard for evaluating non-destructive testing methodologies and fatigue durability performance, the standard comprising:
- a single void-defect coupon that includes:
- (i) a spheroidal void, having a maximum dimension and a spheroidal void volume;
- and
- (ii) an elongated void, having a longitudinal dimension, a maximum transverse dimension, and an elongated void volume;
- wherein:
- (i) the longitudinal dimension of the elongated void is greater than the maximum dimension of the spheroidal void;
- and
- (ii) the maximum transverse dimension of the elongated void is less than the maximum dimension of the spheroidal void;
- wherein the single void-defect coupon is a first single void-defect coupon, and further wherein the standard comprises a second single void-defect coupon that comprises:
- a second-coupon spheroidal void, having a maximum dimension and a spheroidal void volume;
- and
- a second-coupon elongated void, having a longitudinal dimension, a maximum transverse dimension, and an elongated void volume;
- wherein:
- (i) the longitudinal dimension of the second-coupon elongated void is greater than the maximum dimension of the second-coupon spheroidal void;
- (ii) the maximum transverse dimension of the second-coupon elongated void is less than the maximum dimension of the second-coupon spheroidal void;
- and
- (iii) the spheroidal void volume of the second-coupon spheroidal void is greater than the spheroidal void volume of the spheroidal void of the first single void-defect coupon.
