Classical continuum damage theory for quasi-brittle fracture exhibits an extreme sensitivity to the fineness and orientation of the spatial discretization in finite element simulations. This sensitivity is caused by the fact that the mathematical description becomes ill-posed at a certain level of a

We know from experimental phenomena that the ductility of materials decreases with increasing numbers of cycles in the process of cycle fatigue loading, from which a new fatigue damage variable D \* based on the material ductility property is defined.

To avoid the well-known drawbacks of the classical continuum damage theory when localization occurs, an isotropic gradient-enchanced damage model is proposed in which the loading function not only depends on the damage value, but also on its Laplacian.

Regrettably, we have found some errors and inaccuracies in our paper on interpolation requirements for implicit gradient-enhanced continuum damage models. A list of corrigenda follows below.

## Abstract Some properties of a gradient‐enhanced continuum damage model were discussed by means of a numerical and theoretical study. In particular, it is demonstrated that the discretization of this model does __not__ belong to the class of mixed finite element formulations (although the model h

Abstnct-A continuum damage ma%nics model for low-cycle fatigue is presented. The rupture time of hot rolled type RS50 steel is predicted by the damage model and compared with those measured with excellent agreement. It is shown that the proposed damage model can predict the rupture time of material
