The change in temperature is taken as 25 K, the nonlocal parameter is 0.05 and Winkler
elastic constant K is taken as 0 MPa.
The bulk ordering potential W here is constructed by design to have a minimizer (in the class tr(u) = 1) at a perfectly ordered uniaxial state u = n [cross product] n, with [absolute value of n] = 1 but with the direction of n arbitrary, and e is referred to as a "dimensionless
elastic constant." With the help of the relation u = Q + 1/3I, the model can be identified with a certain constrained form of (1.1).

Elastic constants, piezoelectric constants, and dielectric constants of BaTi[O.sub.3] crystal.
Previous researchers have found differences in the
elastic constants and
elastic constant ratios of structural size solid-sawn lumber and structural composite lumber (SCL) materials using a variety of bending and torsion test methods.
Elastic constants of continuous fiber reinforced composites with various types of constituents were determined by Hashin & Rosen [1], Hashin [2], Whitney [3] and Chen and Chang [4].
4) Based on these strains, find the hypothetical
elastic constants by using Eqs.
where [x.sub.h](t) is the homogeneous solution, [x.sub.p](t) is the particular solution, [F.sub.0] is the harmonic force, [omega] is frequency that can be described as [omega] = 2[pi]/T (T is the period of oscillation), k is the
elastic constant, m is the mass, and [[omega].sub.n] is the natural frequency given by
