Experimental study on creep failure characteristics of coal mass under multistage stress and construction of prediction model

open access: yesFrontiers in Earth Science, 2023
The creep and failure mode of stratified coal is complex and challenging to predict. This is highly attributed to the internal stratified structure generated during coal forming.

The Effect of Specimen Size and Test Procedure on the Creep Behavior of ME21 Magnesium Alloy

open access: yesCrystals, 2021
Lightweight constructions and materials offer the opportunity to reduce CO2 emissions in the transport sector. As components in vehicles are often exposed to higher temperatures above 40% of the melting temperature, there is a risk of creep.

Thermal creep behavior of CZ cladding under biaxial stress state

open access: yesNuclear Engineering and Technology, 2020
Thermal creep is a key property of zircaloy cladding. CZ developed by CGN is a new zircaloy used as PWR fuel cladding. This research is devoted to investigating the thermal creep behavior of CZ and build the thermal creep model of CZ.

A Fractional Order Creep Damage Model for Microbially Improved Expansive Soils

open access: yesFrontiers in Earth Science, 2022
Microbial Induced Calcite Precipitation method was used to improve the expansive soils of Nanning, Guangxi. The nonlinear shear creep behavior of microbially improved expansive soil was studied by triaxial consolidation drainage shear test.

Review on Creep Phenomenon and Its Model in Aircraft Engines

open access: yesInternational Journal of Aerospace Engineering, 2023
The aircraft is subjected to high-temperature and high-pressure conditions during flight, which renders it susceptible to the occurrence of creep phenomenon. Several academics have conducted extensive research on this issue.

The dual nature of TDC – bridging dendritic and T cells in immunity

open access: yesFEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

New Maxwell Creep Model Based on Fractional and Elastic-Plastic Elements

open access: yesAdvances in Civil Engineering, 2020
Creep models are mainly used to describe the rheological behaviour of geotechnical materials. An important research focus for studying creep in geotechnical materials is the development of a model with few parameters and good simulation performance ...
