note = {A new stability-instability criterion (named T_ε(T^*_ε) criterion) for crack growth which is
applicable to small scale yielding cracks and also to large scale yielding cracks is proposed
based on crack energy density concept. T_ε criterion is a criterion in which attention is paid to the rate of variation of crack energy density at a crack tip point of every moment, and T^*_ε criterion is another version of T_ε criterion and is a criterion in which attention is paid to the rate of variation of crack energy density at a fixed point which will be a new crack tip point after extension. The relations between T_ε(T^*_ε) criterion and other known criteria (criterion based on g-R-a curves; T_j, T_δ and T_W criteria) are also discussed and it is shown that the physical meanings of other criteria can be made clear and all criteria can be systematized based on the new criterion.},
