For example, during the beginning stage of a constant-strain-rate tension, the volume strain shows a small reduction, which is beyond understanding because on the base of the classical mechanics there could be not the reduction of volume strain in stretching process.
Together with the phases, the signs of the co-seismic amplitude change as well as the co-seismic and post-seismic patterns of volumetric strain and water level, we obtain the coupling mechanism of the volume strain change and the water level change: Before the earthquake, tidal volumetric strain induced the change of water level (the phase of the water level lagged behind that of the volume strain).
R] is the volume strain in the rubber particles, G is the surface energy of the rubber phase, and the function F([lambda.
Under hydrostatic compression, the bulk modulus (B) is defined as the ratio, hydrostatic pressure to volume strain (ref.
0 Tohoku earthquake produced huge-energy teleseismic waves, leading to an extreme decrease of volume strain and an abrupt increase of water level in the aquifer at far fields (epicentral distance >1800 km).
12] proposed the use of rectangular bars that contained a section of slightly reduced width to increase the resistance to necking, thus raising the volume strain generated by the tensile loading.
The volume strain was measured and chosen as a damage indicator.
iii) the axial strain in the RVE by interpolating the above strain distribution, and (iv) the volume strain in the RVE by simply computing the trace of the strain tensor, [[epsilon].
Gloaguen and Lefebvre [40] measured the volume strain of PA nanocomposite samples during deformation.
Acoustic emission and volume strain measurements were used for this purpose, which can identify local deformations and the consequent volume increase.
However, it was difficult until recently to determine quantitatively the contribution of damage mechanisms to the overall strain in the plastic range, especially because available techniques were inefficient to measure volume strain after the initiation of necking.
