Review of Creep Cavitation and Rupture of Low Cr Alloy and its Weldment [PDF]

, 2013
This paper presents a review of creep cavitation and rupture of low Cr alloy and its weldment, particular in the heat-affected zone (HAZ). Creep damage is one of the serious problems for the high temperature industry.

Uniaxial Creep Test Analysis on Creep Characteristics of Fully Weathered Sandy Shale

Processes, 2023
The creep damage behavior of rocks is very important for evaluating the stability and safety of key rock engineering. Based on the Lianhua Tunnel Project in China, this paper aims to study the creep damage mechanics, the influencing factors and the creep constitutive models of sandy shale.

Shear creep mechanical properties and damage model of mudstone in open-pit coal mine

Scientific Reports, 2022
Clarifying the shear creep characteristics of rock and scientifically analyzing its creep deformation law is the key to solving the problem of safe construction and long-term stability analysis of the open-pit coal slope rock mass. Shear creep tests were

A novel nonlinear creep model based on damage characteristics of mudstone strength parameters.

PLoS ONE, 2021
Mudstone interlayer is a weak layer in rock engineering. When it is subjected to continuous stress higher than its damage threshold, due to the dislocation of particles in mudstone crystals and the expansion of cracks, mudstone strength is gradually ...

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

Frontiers 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.

Creep Characteristics of Weathered Soils and Application of Singh-Mitchell's Creep Formula [PDF]

Journal of The Korean Society of Agricultural Engineers, 2009
Soils exhibit creep behavior in which deformation and movement proceed under a state of constant stress or load. In Korea, weathered soil is abundant and occupies around one-third of the country. Weathered soil is visually described as a sandy or gravelley soil, but the behavior is quite different from the behavior of usual sand and gravel.
