Abstract: | Accepted views concerning Poisson's ratio for central-force polycrystals are amended. For pulycrystals the ratio can vary from 1/4, which is actually a lower limit. An upper limit of Poisson's ratio exists also. Both limits can be calculated from single-crystal elastic data. The limits correspond to Voigt's and Reuss's states of uniform local strain and of uniform local stress, respectively. |
