Faria, R.; Oliver, J.; Cervera, M. A strain-based plastic viscous-damage model for massive concrete structures. (English) Zbl 0920.73326 Int. J. Solids Struct. 35, No. 14, 1533-1558 (1998). Summary: Within the framework of continuum damage mechanics, we present new constitutive damage model for massive concrete, mainly intended for the seismic analysis of gravity and arch dams. Consistent with thermodynamic requirements, a strain-driven formalism is adopted, improving the algorithmic efficiency as much as required for the analysis of large scale problems to become feasible. We introduce two scalar damage variables as internal variables, as well as a plastic-strain tensor. An extension to account for the concrete strain-rate dependency, suitable for seismic analysis, is presented at the end. The efficiency of numerical predictions from the model is illustrated through numerical applications.
