Application of the Normalization Method to Various Fracture Toughness Specimens


Application of the Normalization Method to Various Fracture Toughness Specimens

Dzugan, J.; Viehrig, H.-W.

The objective of this paper is the evaluation of the normalization method performance compared to the conventional standard method for a broad spectrum of different materials and specimen geometries. The normalization method based critical J-integral values were summarized and compared with the results of the unloading compliance tests. The results point out the applicability of the normalization method for the J-R curve determination for the investigated materials. The normalization method provided results with up to 15 % deviation from the values obtained with the unloading compliance method.

Keywords: fracture mechanics; fracture toughness; normalization method; unloading compliance
