Abstract:

Finite element calculations show that elastic displacements along the bottom surface of a three-point bend specimen can be used to obtain a close approximation to the load-line displacement at the crack line. The use of load- line displacement for measuring crack growth by unloading compliance is discussed with application to a simplified test procedure for J-integral fracture toughness tests. JS
