| Abstract: | The general form of the third-order nonlinear elastic coefficient tensor having the symmetry of the group SO(2) was derived with the help of group theoretical methods.It is indicated that the third-order nonlinear elastic coefficient tensor for quasicrystals with ten-fold symmetry axis has an arbitrary rotation symmetry about the ten-fold axis. |

| Keywords: | quasicrystal third-order nonlinear elasticity axial rotation symmetry |
