Abstract:
A method of testing a material sample of a type used in a wall of a structure in a standard test for in-plane fracture toughness evaluation. The method comprises obtaining a sample having a lateral length no larger than a thickness of the wall of the structure, shaping the sample to have (a) a bottom surface, (b) a profiled top surface having a central notch, (c) a first coupling feature on a first side of the central notch, and (d) a second coupling feature on a second side of the central notch, assembling a test specimen which increases the width of the sample beyond the lateral width by coupling a first lateral extension to the first coupling feature and a second lateral extension to the second coupling feature, and applying a standard fracture toughness test to the so-assembled test specimen and sample to evaluate the fracture toughness of the sample.

Claim (Index 16):
An apparatus for testing a material used in a wall of a structure for fracture toughness, the apparatus comprising:\n a notched component made from a sample of the material of the structure shaped to have (a) a bottom surface having a width equal to a thickness of the wall of the structure, (b) a profiled top surface, the profiled top surface having a central notch, (c) a first socket on a first side of the central notch, and (d) a second socket feature on a second side of the central notch; a first lateral extension coupled to the first socket of the notched component; and a second lateral extension coupled to the second socket of the notched component, wherein the first and second lateral extensions extend an effective width of the notched component to provide an assembled test specimen of sufficient length to be used in a standard fracture toughness test.
