Creep damage descriptionsViscoplasticityNonlinear geometryConstitutive equationsComputationLarge time increment methodThis paper deals with a numerical analysis of creep components until failure. We will take an interest in the macroscopic modeling of the creep curves with its three stages based on the ...
the threshold for accelerated creep strain (viz., when the maximum load was applied), the sequence initiated with the initial creep stage, progressed to a steady stage quickly, and then to an accelerated stage, all preceding creep failure, which reflected the three stages of creep deformation. ...
which is usually accompanied by the cracking, rockburst and other damages of the surrounding rock1,2. Surrounding rock failure and instability are essentially the evolution process of rock mass meso-damage to macro-cracks in the process of stress adjustment. Moreover,...
Influences of multiaxial creep deformation and rupture behavior on 304HCu austenitic stainless steel have been investigated on carrying out creep rupture test on both smooth and notch specimens at 1023 K over a wide range of stress (100-200 MPa). Creep rupture strength exhibited an increasing trend...
Uniaxial compression tests and cyclic loading acoustic emission tests were conducted on 20%, 40%, 60%, 80%, dry and saturated muddy sandstone by using a creep impact loading system to investigate the mechanical properties and acoustic emission characteristics of soft rocks with different water conten...
To characterize the effects of creep, strain rate, and relaxation in granular soils, different sands have been studied under oedometric loading. The tests were analysed in the framework of the isot...
30% and 40%, which are denoted\(S_{20}\),\(S_{30}\)and\(S_{40}\), respectively. The expansive soils with different moisture contents were compacted in layers to form a slope model with a compaction degree of 79%. The model preparation process was divided into four stages, as show...

“creep” toward one side of the compartment in which it is located. Rather, the angle of attack of the femoral condyle and/or tibial plateau bearing surfaces against the device will ensure that the device reversibly translates during articulation, maintaining the device, on average, in the ...
e., small additions of boron inhibit damage in the grain boundaries during creep. In samples of steel Kh17N13M3T with 0.0015% B, with the highest long-term strength, the size of the blocks formed in the process of creep is smaller than in the steel without boron or with 0.003% B. ...
