A B S T R A C T In this review paper, only constraint and stress gradient approaches to transferability of fracture toughness are examined. The different constraint parameters are defined and discussed, and one example is given in each case. Factors that influence the constraint are studied. Special attention is given to the actual trends to use the plastic constraint in the material failure master curve and the material transition temperature master curve. The paper also deals on the influence of T stress on the crack path and out-of-plane constraint and on the influence of thickness on fracture toughness. The uses of plasticity with gradient and the relative stress gradient in local fracture approaches are also examined.A = constant A i = Williams' stress distribution parameterŝ A i = HRR stress distribution parameters A P = Constraint parameter A p,c = current plastic zone area A p,ssy = reference plastic zone area A εp,c = area surrounded by the equivalent plastic strain A εp,ref = reference area surrounded by the (ε p ) isolines B = thickness B 0 , B 1 , B 2 and B 3 = constants D = pipe diameter D 0 = length E = Young's modulus F = geometry correction factor G = shear modulus G c = fracture toughness I = complex function of eigenvalues I n = dimensionless integration constant J = path integral J c = fracture toughness J Ic = fracture toughness in plane strain conditions J ref = reference fracture toughness K Ic = fracture toughness for plane strain conditions K Jc = fracture toughness K Iz,c = three-dimensional fracture toughness in pure mode I K 0 = lower bound of the notch fracture toughness K ρ,c = notch fracture toughness K 0 ρ;c = fracture toughness corresponding to T ef,c = 0 L = plastic constraint factor N = strain hardening exponent

We have developed a new approach to the evaluation of the capability of steels to resist brittle fracture based on the physical ideas concerning the micromechanism of transition of metals from the plastic state into the brittle state. Within the framework of this approach, we propose new microscopic characteristics of stability of the metal, namely, the parameter of mechanical stability and the coefficient of mechanical stability. The procedure of experimental evaluation of these parameters is described and the relationship between the coefficient of mechanical stability and standard characteristics, such as plasticity under uniaxial tension and impact toughness, is analyzed in detail. We introduce a new characteristic called the force equivalent of embrittlement, which enables us to describe, on a single scale, the embrittling action of the following factors of different physical nature: complex stressed state, stress concentration, low temperatures, and dynamical loading. We propose a criterion aimed at the description of stability of the plastic state of the metal at the tip of a macrocrack and develop a procedure of experimental determination of the value of force equivalent of embrittlement for a standard cracked specimen. For the typical representatives of low-, medium-, and high-strength structural steels considered as an example, we study the regularities of the influence of the strength of a steel on the value of the coefficient of mechanical stability. On the basis of these data, we compare structural steels from the viewpoint of their stability under the embrittling action of cracklike defects.
