The crack tip opening angle (CTOA) has been used as a reliable fracture toughness to
characterize stable crack growth for thin-wall structures in low-constraint conditions …

In the present work, the normalization (NM) method was used to obtain J integral resistance
(JR) curves based on clamped single edge notched tension (SENT) specimens. The SENT …

In structural integrity assessment based on the two-parameter approach with considering
constraint, it is an important step to establish a correlation between fracture toughness and …

Unloading compliance method (UC) and normalization method (NM) are two of the most
commonly used methods for determining the fracture toughness of steels. Since the NM has …

Normalization method is more convenient than unloading compliance method in
determining J-resistance (JR) curve and fracture toughness of steel. However its …

In this research, a higher-order asymptotic JA 2-A 4 solution was introduced for studying the
effect of the bending moment on the crack-tip constraint of a specimen. The solution was …

Normalization method (NM) is a practical method for determining the J–R curves and
fracture toughness of steels. There is some concern, however, about the performance of this …

Nuclear reactor fuel pins act as barriers to the release of radioactive fission products to the
coolant flowing around these thin-walled tubes and hence they prevent the leakage of …

In this paper, the fracture toughness tests of compact tensile (CT) specimens with varying in-
plane constraints were carried out. JR curves of G20Mn5QT cast steel were firstly measured …

This study successfully deals with the inhomogeneous dimension problem of load
separation assumption, which is the theoretical basis of the normalization method …
