What is Polished notch modification of SENB-S fracture toughness testing about?
A bstruct ## In fracture toughness testing it is common for reasons of simplicity and reproducibility to use notches to approximate sharp cracks. However, a dependence of measured fracture toughness (K,) on notch-root radius is observed. This can be explained as a consequence of the interaction of a distorted stress field with material flaws in front of a notch. ## A relationship to quantify this e#ect is presented and examined. It is shown that to measure true fracture toughness sharp notches of the size of microstructural features are required. A simple method to make very sharp notches is presented. Fracture toughness values determined with sharp-notched samples are compared with the results of experiments with conventional sawn-in notches. It is shown that sharp notches deliver considerably lower, more accurate and reproducible values qf KI, for materials with fine microstructures. These values are thought to lie at the beginning of any R.-curve.
