Damage evolution and recrystallization enhancement of frozen loess
TL;DR: A series of multistage triaxial compression, creep, and stress relaxation tests were conducted on frozen loess at the temperature of −6℃ in order to study the damage evolution and recrystallization as mentioned in this paper.

Creep damage and life assessment of thick-walled spherical reactor using Larson–Miller parameter
Abbas Loghman,Mehdi Moradi +1 more
TL;DR: In this paper, the authors used the Robinson's linear damage accumulation rule to obtain damage and remnant life assessment in which time to rupture is determined by Larson-Miller Parameter (LMP).

Rupture Time Under Creep Conditions
TL;DR: In this article, a theoretical model for the time to rupture with the account of embrittlement was proposed, and the experimental data points typically lie below the theoretical predictions and rupture occurs at elongations not exceeding several tens per cent.

Constitutive equations for creep rupture
F. A. Leckie,David R Hayhurst +1 more
TL;DR: In this paper, a phenomenological approach to the Rabotnov-Kachanov equations is presented, which describes the growth of creep damage in metals and the effect of this damage on creep strain rates.

Tertiary creep in nickel-base superalloys: analysis of experimental data and theoretical synthesis
B.F. Dyson,T.B. Gibbons +1 more
TL;DR: In this article, a more substantial range of data for alloys of this type is presented and it is concluded that ductility in creep is the most significant parameter correlating differences in rates of strain-accumulation in the tertiary stage: thus, the lower the ductility the greater the rate of strain accumulation.
