| Abstract: | In this comment, it is pointed out that the paper Li and Mataga, 1996. J. Mech. Phys. Solids 44, 1799-1830], which presents original and valid solution strategy for an important problem of dynamic crack propagation in piezoelectric materials, contains ultimate quantitatively and qualitatively incorrect expressions, conclusions and plots due calculation errors. The correct calculations and corresponding correct conclusions and plots are presented. |
