This is due to the relatively high voids between the large gangue particles, resulting in a greater compression space for the gangue sample during the compression process. The initial stage of axial stress loading with the same confining pressure. The axial creep and volumetric creep of the ...

5). Stress relaxation and creep results indicated that while the leaflet tissues exhibited significant stress relaxation, they exhibited negligible creep over the three hour test duration. To our knowledge, this response is unique in the biomechanical literature and stands in contrast, for example, ...
sampletablesupportsystemairbeatingCENTERA support system is the main load-bearing component of sample table for neutron stress spectrometer, and air bearing is an important element of a support system. The neutron stress spectrometer sample table was introduced, and the scheme for air bearing ...
maximum axial load under which the sample is able to remain stable during long-term loading50,51. Here, the transitional creep method52is introduced to predict the long-term strength. The ratio of the shear strength to the long-term strength can be defined as the normalized failure stress. ...

The IWIN Ev2 Plate Bearing Test Equipment is suitable for testing the foundation coefficients of coarse and fine grained soil and subgrade and base course after compaction, and can also be used for calculating the deformation modulus of uniform foundation. Test the st...
Meanwhile, according to mineralogical research, the cataclastic structure is widely developed in the southeastern part of the study area, which indicates that the rocks may have undergone relatively strong tectonic stress [34,105]. In addition, the experimental petrological evidence shows that chromite...
The most common failure causes of bearings are as follows: fatigue pitting refers to the phenomenon that the surface material is prone to partly falling off under the action of stress when the bearing is running; plastic deformation refers to the fact that the raceway is indicated by a large ...
