Anisotropic modelling and numerical simulation of brittle damage in concrete. (English) Zbl 0836.73055
A framework for damage mechanics of brittle solids is presented and exploited in the design and numerical implementation of an anisotropic model for the tensile failure of concrete. The key feature exploited in the analysis is the hypothesis of maximum dissipation, which specifies a unique damage rule for the elastic moduli of the solid once a failure surface is specified. A three-surface failure model for concrete, containing essentially no adjustable parameters, is shown to produce results in agreement with experimental data.
