Return to previous page. 1. Equal Poisson ratio 2. vLm/vLp vs. ρ/ρ version of this page 3. Poisson ratio of matrix greater than nanoparticle 4. Actual material combinations |
For all the examples on this page, the nanoparticle
has a greater Poisson ratio than the matrix.
That means that
vTp / vLp
< vTm / vLm. |

Figure 2(a) sph0cn15.cpp md5447q.gif md5447k.gif Notice in the left figure that the dimensionless frequency ξ varies continuously from FSM to BSM as the diagonal is crossed. The Poisson ratios correspond roughly to a gold nanoparticle in a diamond matrix. This continuous variation of ξ is an unusual situation. |

Figure 2(e) sph0cn15.cpp md5427q.gif md5427k.gif Note the effect of a large difference in Poisson ratio. Q is never small and the transition from FSM to BSM is smooth. |
