Influence of ZnO on its
elastic moduli and comparison of
elastic moduli obtained experimentally and
elastic moduli obtained theoretically were also discussed.
Therefore, LBs have the highest
elastic moduli as well, with 86.27 GPa, 35.20 GPa, 99.31 GPa, and 52.38 GPa for LB4's E, G, L, and K, respectively.
The
elastic moduli plotted based on the theoretical model in Figure 3 show similar trend to the experimental results.

elastic moduli in dependence on orientation and temperature up to 2000[degrees]C," Review of Scientific Instruments, vol.
After the annealing, neither the uniaxially stretched nor magnetically oriented films exhibited a remarkable increase in
elastic moduli measured at room temperature.
The elastic modulus of the magnetically oriented films was lower than that of the mechanically oriented films of the same orientation degree, but it was comparable to or even higher than the
elastic moduli of the mechanically oriented films of lower orientation degrees.
Therefore, we conclude that the series and parallel coupling schemes of the aggregate model can only provide bounds, and it is not justified to use either scheme to obtain precise values for the
elastic moduli. Table 1.

elastic moduli of two-phase materials," Journal of Applied Mechanics, vol.
(2) The
elastic moduli of the directionally distributed SFRC given by the theory of composite materials and the semiempirical formulas all differ from the experimental values.
Since for porous material
elastic moduli is a function of porosity [15, 16], ultrasound velocity in homogeneous material would depend on porosity.
Rodriguez, Queiroz, Espinosa, and Zandonadi (2006) determined the
elastic moduli of coffee stems by considering the stems as cantilever beams with a concentrated mass at the free end.
Curves were plotted using Microsoft Excel for each material for comparison The results showed that the
elastic moduli increased at all times in the following order; Cavex Cream Alginate(r)> Tulip(r)> Cavex Color Change(r)> TOL (r)> Cavex CA37(r) and the rate of increase was greater at the end of working time, and later decreased.
