Important advances in creep damage models for crack growth analysis have been made in
the last two decades as scientists and engineers strive to imbue continuum-based models …

The existence of multi-axial states of stress cannot be avoided in elevated temperature
components. It is essential to understand the associated failure mechanisms and to predict …

316L type stainless steel is widely used in chemical industries due to its excellent resistance
to corrosion. But the welding residual stresses have a great effect on stress corrosion …

This work involves a mechanistic investigation of the high temperature behaviour of a
commercial high-Cr martensitic steel (P91), focussing particularly on the size effects of M 23 …

Creep rupture life of 9Cr–1Mo steel under multiaxial state of stress has been assessed.
Stress multiaxiality in cylindrical specimens during creep tests has been introduced by …

This paper deals with the determination of material constitutive model for P91 and P92
steels at high temperatures. An isothermal, strain-controlled test programme was conducted …

This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material.
A multi-material model is developed for high temperature cyclic plasticity, including the …

Materials in engineering applications are rarely uniaxially-loaded. In reality, failures under
multiaxial loading has been widely observed in engineering structures. The life prediction of …

It is well accepted that the second law of thermodynamics describes an irreversible process,
which can be reflected by the entropy increase. Irreversible creep and fatigue damage can …

The creep crack growth (CCG) behavior and loading mode coupled with the initial small
cracks distributed within the weldments play critical roles in the failure mode of thick-walled …
