In elastic mechanics using Poisson's ratio and axial strain
to calculate volume strain is the most common method for brittle rock.
05% strain) to red (higher strain values of 2% strain) was used on the DIC images illustrating the axial strain
The axial strain
was measured by a uniaxial extensometer with a gage length of 10 mm.
The ratio of the increment of deviatoric stress corresponding to the axial strain
Figure 13 shows the relationship between the axial strain
in compression (or tension) reinforcing bar at 3% drift and [l.
The main objective of the present study is to introduce a novel approach for the mechanical analysis of cylindrical cavity expansion considering the influence of the axial stress based on the assumptions of the quasi-plane strain-softening problem, and the corresponding theoretical solutions for the deformation-dependent intermediate principal stress and axial strain
2b the maximum and minimum values for the axial strain
due to bending are plotted.
Biaxial strain testing is necessary to determine Poisson's ratio, which is the negative ratio of transverse to axial strain
is measured in the middle part of the specimen using three extensometers placed at 120[degrees].
In calculations it is recommended to increase gradually concrete's axial strain
Two pairs of orthogonal cantilevers were used to measure diametral strain, while a pair of LVDTs measured axial strain
Also, the level of vertical or axial strain
reduction has reduced with the increase in the applied lateral gas confining pressure.
