Positive-definite conditions of elastic constants of two-dimensional quasicrystals with noncrystallographic symmetries.
In the present work, the positive-definite conditions of the elastic constants of two-dimensional (2D) quasicrystals with non-crystallographic symmetries have been derived. These results are necessary for studying elastic and mechanical properties of two-dimensional quasicrystals both in theory and in experiment.
