Figures 6(a)-6(d), respectively, show the relationships between the differential stress
([[sigma].sub.1] - [[sigma].sub.3]) and principal strain ([[epsilon].sub.1], [[epsilon].sub.2], and [[epsilon].sub.3]) as well as volumetric strain ([[epsilon].sub.V]) under true triaxial compression.
Under the condition of triaxial compression, the axial principal stress was the differential stress
[[sigma].sub.1] - [[sigma].sub.3].
The flow field, including velocity field and stress field, can be calculated via the above flow equation, and then deviatoric stress and horizontal differential stress
on the oil film and residual oil deformation can be calculated.
They treated the fibrochondrocytes of pig Achilles tendon with differential stress
and found that the proliferation and differentiation of fibrochondrocytes are affected by cyclic stress tensile.
The larger the degree of bend, the greater the differential stress
from inside radius to outside radius.
* critical differential stress
([[sigma].sub.1] - [[sigma].sub.3]),
Starvation differentially protects normal cells but not cancer cells against oxidative stress and chemotherapy drugs, this phenomenon is termed differential stress
3a the differential stress
is plotted against axial strain up until just before final failure.
Longo coined the term differential stress
resistance (DSR) to describe the ability of STS to trigger protective reactions in healthy cells but not in cancer cells.
The system, a 256 x 256 array of bimetallic actuators, has a high sensitivity (detectivity > [10.sup.10] cm x [Hz.sup.1/2]/W), since it can detect bending due to differential stress
in each actuator (microcantiliever) at subnanometer levels.
The MC gradients cause differential stress
inside the kernel, which, if sufficiently large, causes the kernel to fissure.
