The sensor has better anti-interference and higher accuracy than others, can measure a range of 0 kPa to 20 kPa of microstress, and has good linearity (Figure 5).

where [[bar.[xi]].sup.(k).sub.11] is microstress caused by single principal macrostress [[sigma].sub.k], then dispersion D ([[xi].sub.11]) can be found as sum of three dependent random quantities:
where [sigma] is the macrostress (Piola-Kirchhoff stress), [eta] is the microstress and [tau] is the interactive force.
Carbon atoms dissolved in the octahedrical positions of martensite reduce the size of domains and increase the size of structural microstress, as demonstrated by the results of the X-ray analyses.
where [t.sub.ij] is the stress tensor, [m.sub.ij] is the couple stress tensor, [[pi].sub.i] is the microstress vector, [sigma] is the scalar microstress function, [epsilon] ijk is the alternating symbol and A ijrs,B ijrs,C ijrs,D ijr, [E.sub.ijr], [a.sub.ij], [b.sub.ij], [c.sub.ij], [d.sup.i], [xi] are constitutive coefficients which satisfy the symmetry relations
where the macrostress [sigma], the microstress [eta], and the interactive force [tau] are defined as derivatives of the free energy function
Here u denotes the macrodisplacement, [psi] the microdeformation, [rho] the macrodensity, I the microinertia, [sigma] the macrostress, [eta] the microstress, [tau] the interactive force, x space coordinate, and t time.
The frame was analyzed using Microsafe 3-D (Microstress Corp.
where [M.sub.s] is the spontaneous saturation magnetization of the domains per unit volume, A is a constant representing the contributions of inclusions and microstress, B is a constant representing the contributions of magnetocrystalline anisotropy, and [X.sup.H] is the forced magnetization term.
Accordingly, the lattice decline was believed to result from a release of intrinsic microstress.
