Consequently, it can be applied to any physical property, including the residual deformation and relaxation, or in the case of a complex time dependence of the property.
The coal sample retains some residual deformation: the greater the equilibrium pressure, the larger the residual deformation.
The first hysteresis loop is not closed, and a large residual deformation occurs between the two curves.
Tenders are invited for Supply of benchmarks for the control of residual deformation of steam pipelines of TPP OST 108.837.01-82
There was no residual deformation of the cortical endplate.
Hence, the premise is to obtain the residual deformation of the pavement by calculating the stress distribution of the load.
Although the stress-induced martensitic transformation occurs in the specimen annealed at 823 K, there is residual deformation after unloading, mainly because of the irreversible strain between nucleated martensite and austenite as well as influence by the sharpness of the indenter tip [24].
[15]; the results demonstrated that the residual deformation of prestressed concrete assembly frame joints is less than that of cast in situ concrete joints, and the cracking resisting capacity, stiffness, and deformation recovering capacity of the core joint regions of the assembled specimens are better.
Since residual deformation generated from the first test changed cross-sectional area of the specimens, strain, and engineering stress from the second test could be calculated based on either the cross-sectional area of the virgin specimens, i.e., before the first test, or the cross-sectional area at the beginning of the second test.
Low-temperature properties of the binder were compared with the indices, standardized by GOST 52056-2003 (Table 3) and additionally by the method of determining the residual deformation proposed in this paper, since the occurrence of this type of deformation is especially dangerous for asphalt concrete pavements.
That is to say, the seismic residual deformation of the dam, which is important for the seismic design of high CFRDs, cannot be obtained directly by this method, especially the deformation history.
Neutron diffraction strain probing in SALSA did permit to estimate elastic residual deformation in specimens of a commercial aluminum alloy (AA-5083) processed by ECAP.
