GE399-353 ASTM E399 Test Fixture


Model# GE399-353

The GE399-353 clevis grip meets the requirements of ASTM E399 for determining the linear-elastic plane-strain fracture toughness of metallic materials. GE399-353 clevis grips can be used for both fatigue precracking and fracture toughness components of ASTM E399 testing for compact tension C(T), disc shaped tension DC(T), and arc shaped tension A(T) specimens. Crack opening displacement gages for measuring the fatigue crack opening are sold separately.

ASTM E1922 specifies clevis fixturing of the same type as ASTM E399. Reference ASTM Standard E 399, 2008, Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness KIc of Metallic Materials, West Conshohocken, PA, 2008
