TLDR
In this article, the Weibull stress criterion is applied to correct the CTOD for constraint loss, which leads to an equivalent CTOD ratio, β, defined as β = δ/δWP, where δ and δWP are CTODs of the standard fracture toughness specimen and the structural component, respectively.About:

Development of benchmark reduced activation ferritic/martensitic steels for fusion energy applications
Hiroyasu Tanigawa,Ermile Gaganidze,Takanori Hirose,M. Ando,Steven J. Zinkle,Rainer Lindau,E. Diegele +6 more
TL;DR: In this paper, the current status of reduced activation ferritic/martensitic (RAFM) steels is reviewed based on two leading RAFM steels, F82H and EUROFER-97.

Structural integrity assessment of components subjected to low constraint conditions
TL;DR: In this paper, the authors proposed a fracture assessment methodology which takes into account in-plane loss of constraint, which is referred to as the loss-of-constraint.
A Probabilistic Model for Cleavage Fracture with a Length Scale
TL;DR: In this paper, a probabilistic model for the cumulative probability of failure by cleavage fracture with a material related length scale is developed, which aims at describing the random nature of fracture in ferritic steels in the brittle-to-ductile transition temperature region.

Engineering approaches for the assessment of low constraint fracture conditions: a critical review
TL;DR: In this article, an overview of these methodologies is presented, with special emphasis on the European FITNET Fitness-for-Service (FFS) procedure proposal for the assessment of loss of constraint and also on Japanese IST methodology.

Beremin model: Methodology and application to the prediction of the Euro toughness data set
TL;DR: In this article, a short and efficient way to apply the original Beremin model, published in 1983, to predict the scatter in the brittle part of the brittle-to-ductile transition curve of ferritic steels is presented.

A Local Criterion for Cleavage Fracture of a Nuclear Pressure Vessel Steel
TL;DR: In this article, a local criterion based on Weibull theory was proposed to determine the mechanical conditions for cleavage fracture at the crack tip of A508 class 3 steel, and the results can be accounted for in terms of the local criterion which takes into account the effect of plastic strain.

Family of crack-tip fields characterized by a triaxiality parameter—I. Structure of fields
Noel P. O’Dowd,C. F. Shih +1 more
TL;DR: In this article, a two-parameter fracture mechanics approach for tensile mode crack tip states in which the fracture toughness and the resistance curve depend on Q, i.e., JC(Q) and JR(Δa, Q), is proposed.

The Spread of Plastic Yield from a Notch
TL;DR: In this article, the authors made a calculation of the length of plastic zone needed to accommodate a given plastic displacement at the root of a notch in a uniformly stressed solid, and concluded that a condition of ''far-reaching'' yield should replace the condition of general yield for starting a fracture.

Assessment of the integrity of structures containing defects
TL;DR: A number of methods are now available for assessing the integrity of structures containing flaws in all loading regimes as discussed by the authors, and one of these methods is used to define a route for establishing the structural integrity of a structure containing defects.
