The girth weld is the weak link of high-pressure pipeline, which is easy to crack under the
combined action of internal and external loads, defect and stress concentration. At present …

Constraint can be divided into two conditions of in‐plane and out‐of‐plane, and each of
them has its own parameter to characterize. However, in most cases, there exists a …

In the present contribution, the fracture behaviour of specimens made of isostatic graphite
and weakened by inclined key‐hole notches is investigated. Different loading mixities are …

In this paper, the specimens with different geometries and loading configurations were used
to study the unified correlation of in‐plane and out‐of‐plane constraints with fracture …

To investigate the fracture behaviour of polygranular graphite (a quasi-brittle material), crack
propagation in a short bar chevron notched specimen was studied by synchrotron X-ray …

In this study, the fracture resistance of a dissimilar metal welded joint was measured by
single edge-notched bend specimens with different in-plane and out-of-plane constraints …

Crack tip plasticity and fracture toughness are usually connected with T-stresses under
mixed mode I/II loading conditions. By means of von Mises yield criterion, a new analytical …

The crack initiation and propagation characteristics of two medium grained polygranular
graphites, nuclear block graphite (NBG10) and Gilsocarbon (GCMB grade) graphite, have …

Previous studies on multi-axial fracture of metals have shown that the critical J-integral at
fracture may be less than the fracture toughness measured in a standard test. This gives rise …

To develop new fracture assessment methodology to incorporate both in-plane and out-of-
plane constraints, it is desirable to develop unified constraint parameters convenient for …
