Abstract
Standard continuum models do not incorporate an internal length scale, and therefore suffer from excessive mesh dependence when strain-softening models are used in numerical analyses. In this contribution this phenomenon will be analysed and remedied through the use of higher-order continua. To enable an efficient and robust implementation algorithms based on damage and on plasticity theories will be described for higher-order gradient models and for a Cosserat continuum.
