Abstract:
An orthotropic damage model is developed for plain concrete which is valid up to the ultimate load in uniaxial or biaxial tension. The principal damage components are expressed in terms of volumetric damage caused by the growth and coalescence of voids. The evolution of damage is explained in terms of an additional, load-induced porosity that is calculated by considering several distributions of voids. The model is shown to predict accurately uniaxial and biaxial data from independent tests.
