and piezoelectric properties of ordered Sc 0 · 5 Ga 0 · 5 N alloys under compressive and tensile in-plane strain. This alloy is found to exhibit a tremendous piezoelectric response, associated with a phase transition ...
of the system. Each part of the MST, except for the linear ball bush, was manufactured using an aluminum alloy Al-6061. The test model was fixed at the sting head, while the piezoelectric accelerometer (Model ...
surfaces was within 0.05 mm, and the flatness was less than 0.02 mm. During the uniaxial compressive experiment, the axial and the lateral deformation displacement sensors were set to 0 – 5 and 0 –2.5 mm ...
monotonically with increasing strain amplitude as , where n ∼ = 0.003–0.045. The decrease in P-wave attenuation, Q-1p, for dry sandstone is 5 %, but for saturated sandstone there is no change. The analogous ...
battery maintains the vacuum pressure. At the microscope, the device was again connected to the vacuum pressure controller and the valve was opened. Gas flow ( 5 % CO2) to the mini-incubator was initiated ...
. Specifically, the vertical stacking piezoelectric transducer, grounding at the bottom (voltage = 0 V) and exciting at the top (voltage = 110 V), is installed to simulate the source. The sample length, vibrator ...
calculated from (4) and ( 5 ) are approximately equal. The displacement u was estimated using the transmission coefficient of a piezoelectric transducer at the source voltage. The strain interval ...
