Question

During the triaxial test measurements, local strain gauges were attached to the specimens for high quality measurements to be performed. It was revealed that for the sandstone collected from a depth of 80 m and tested at 0.6 MPa of isotropic confining pressure, at a volumetric strain of 3.0x10-1%, the material was still in the linear-elastic range of behavior. If for the given conditions, the specimen has a true Young’s modulus of 0.286 GPa, a Poisson’s ratio of 0.28 and is assumed to be an isotropic material, determine the deviatoric stress which corresponds to the said volumetric strain of 3.0x10-1%.

(b) During the triaxial test measurements, local strain gauges were attached to the specimens
for high quality measurements to be performed. It was revealed that for the sandstone
collected from a depth of 80 m and tested at 0.6 MPa of isotropic confining pressure, at
a volumetric strain of 3.0x10-l%, the material was still in the linear-elastic range of
behavior. If for the given conditions, the specimen has a true Young's modulus of 0.286
GPa, a Poisson's ratio of 0.28 and is assumed to be an isotropic material, determine the
deviatoric stress which corresponds to the said volumetric strain of 3.0x10-1%.
