An implicit gradient-enhanced damage model with the characteristic length which is a stress level dependent parameter is developed. Both displacements and nonlocal equivalent strain fields are approximated using low-order elements. The spurious damage zones and stress oscillation induced by the conventional strain-based gradient damage can be eliminated. Numerical examples are considered to show the accuracy and performance of the developed method.
