An elastic-viscoplastic creep model for describing creep behavior of layered rock
Frontiers in Materials, 2023 To describe the full-stage creep behavior of layered rock accurately, a new elastic-viscoplastic creep model is proposed based on fractional order theory in this manuscript, which consists of a Hooke elastomer, a fractional Abel dashpot, a Kelvin body ...

Review on the current state of developing of advanced Creep Damage Constitutive Equations for high Chromium Alloy [PDF]
, 2012 This paper presents a review of developing of creep damage constitutive equations for high chromium alloy (such as P91 alloy). Firstly, it briefly introduces the background of creep damage for P91 materials.

Stabilizing nanoprecipitates in Al-Cu alloys for creep resistance at 300°C
Materials Research Letters, 2018 Commercial precipitation-hardened Al-Cu alloys are normally used at temperatures below its ageing temperature of ∼225°C, to avoid thermally induced precipitate coarsening and resultant softening.

Spatial repartition of local plastic processes in different creep regimes in a granular material [PDF]
, 2016 Granular packings under constant shear stress display below the Coulomb limit, a logarithmic creep dynamics. However the addition of small stress modulations induces a linear creep regime characterized by an effective viscous response.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Novel direct method on the life prediction of component under high temperature-creep fatigue conditions [PDF]
, 2013 This paper presents a novel direct method, within the Linear Matching Method (LMM) framework, for the direct evaluation of steady state cyclic behaviour of structures subjected to high temperature – creep fatigue conditions.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Research on Creep Model of Roadway Surrounding Rock Based on Variable Creep Parameters
Meikuang Anquan, 2020 In order to study the creep behavior of surrounding rock of Huaying Coal Mine in Sichuan under different confining pressure characteristics, the triaxial creep test of sandstone was carried out by TAW-2000 test system.
