a local stress based approach to fracture following warm pre-stressing
Quantification of the enhancement in cleavage fracture toughness of ferritic steels following warm pre-stressing has received great interest in light of its significance in the integrity assessment of such structures as ...
Comparison of Global and Local Approaches to Predicting Warm Pre-stress effect on Cleavage Fracture toughness of ferritic steels
Potentially both global and local approaches may be used to predicting the effect of loading history on cleavage fracture toughness distribution of ferritic steels. In this paper the dramatic increase in the apparent lower ...
The Role of Constraint and Warm Pre-stress on Brittle Fracture
This paper presents the results of an experimental and numerical study carried out to investigate
the effect of warm pre-stressing on cleavage fracture in ferritic steels using cracked and notched
specimens. ...
PREDICTING HOW CRACK TIP RESIDUAL STRESSES INFLUENCE BRITTLE FRACTURE
A probability distribution model, based on the local approach to
fracture, has been developed and used for estimating cleavage fracture
following prior loading (or warm pre-stressing) in two ferritic ...
COMPARISON OF METHODS FOR PREDICTING THE INFLUENCE OF RESIDUAL STRESSES ON BRITTLE FRACTURE
This paper compares different methods for predicting the
influence of residual stresses on brittle fracture. Comparison is
made between fracture predictions of a local statistical
approach based on the ...
Comparison of Global and Local Approaches to Predicting Warm Pre-stress effect on Cleavage Fracture toughness of ferritic steels
Potentially both global and local approaches may be used to predicting the effect of loading
history on cleavage fracture toughness distribution of ferritic steels. In this paper the dramatic
increase in the ...
A study of Cleavage Fracture of A508 Steel using Round Notched bar specimens
This paper presents the results of an experimental and numerical study carried out to investigate the
scatter in cleavage fracture in A508, a reactor pressure vessel steel, using a local fracture criterion based
on ...
Application of the Local Approach to predict brittle fracture following Local Compression
In this paper application of the local approach to predict the fracture behaviour of A533B ferritic steel at low temperature, in presence of a residual stress field, is investigated. The local approach assumes a Weibull ...
Predicting the influence of residual stresses on brittle fracture using local approach
This paper explores the application of the local approach to
brittle fracture to predict the influence of residual stresses in a
relatively thick pipe. Three different surface flaw sizes were
assumed ...
