Impact of creep-fatigue interaction on divertor tungsten under high heat flux
Nuclear Materials and Energy, 2023 High heat flux as 20 MW m−2 during stationary operation can be foreseen in future fusion devices, leading to recrystallization and thermal creep in tungsten targets. Both recrystallization and thermal creep impact would play significant roles in service.

Creep-fatigue life assessment of cruciform weldments using the linear matching method
, 2013 This paper presents a creep-fatigue life assessment of a cruciform weldment made of the steel AISI type 316N(L) and subjected to reversed bending and cyclic dwells at 550C using the Linear Matching Method (LMM) and considering different weld zones.

Theoretical backgrounds of durability analysis by normalized equivalent stress functionals
, 2003 Generalized durability diagrams and their properties are considered for a material under a multiaxial loading given by an arbitrary function of time. Material strength and durability under such loading are described in terms of durability, safety factor ...

Journal of Materials Research and Technology, 2020 The alternation of creep properties is unavoidable in welded structures after suffering from cyclic damage, which may lead to the premature failure of power plant units and hard to predict. This work is devoted to clarify the influence of prior low cycle

Life Prediction Using the Creep Rupture Data Described by XML
Journal of the Society of Materials Science, Japan, 2004 This research aims at construction of the technology which can carry out sharing of the material databases built in domestic and overseas as common property. The existing material databases are built by an original concept and an original technique, and they are not premised on sharing.

Influence of notch constraint on creep damage evolution and rupture life of grade 91 steel [PDF]
, 2022 Coal-fired power plants must operate at higher temperatures and pressures to achieve maximum efficiency. During operation, components are exposed to a creep environment that can lead to catastrophic failure.

Optimal Design of Mises Truss with Respect to Time to Creep Rapture
Engineering Transactions, 1994 The paper deals with problem of optimal choice of slope angle for bars of Mises truss in creep conditions. Results of optimization with respect to brittle creep rupture coincide with elastic solution (45°), while for ductile creep rupture there is no ...

Influence of axial load on internal pressure creep of Mod.9Cr-1Mo circumferential welded pipe
Nihon Kikai Gakkai ronbunshu, 2015 Mod.9Cr-1Mo steel(P91) is widely used for high temperature pipes in ultra-super-critical thermal power plants. However it was recently reported that the creep damage was detected at heat affected zone(HAZ) in welded joints of the pipes so-called the ...
