Peerlings, R. H. J.; de Borst, R.; Brekelmans, W. A. M.; de Vree, J. H. P. Gradient enhanced damage for quasi-brittle materials. (English) Zbl 0882.73057 Int. J. Numer. Methods Eng. 39, No. 19, 3391-3403 (1996). Summary: Conventional continuum damage descriptions of material degeneration suffer from loss of well-posedness beyond a certain level of accumulated damage. As a consequence, numerical solutions are obtained which are unacceptable from a physical point of view. The introduction of higher-order deformation gradients in the constitutive model is demonstrated to be an adequate remedy to this deficiency of standard damage models. A consistent numerical solution procedure for the governing partial differential equations is presented, which is shown to be capable of properly simulating localization phenomena.
