Rixen, D.J. Simone, A. Sluys, L.J. Stroeven, M. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2009-05-24 Abstract In this study a FETI: Finite Element Tearing and Interconnecting [1] technique is adopted and exploited for the efficient and accurate modeling of softening materials such as concrete and rock. A fie scale analysis in which concrete is modelled as a three-phase material is used. Special attention is given to the treatment of linear and non-linear domains during the analysis. Several optimization enhancements are introduced in order to identify the active non-linear domains and selectively use computational effort. The effect of different decomposition criteria is analyzed in this study. The brittle constitutive behaviour of the above mentioned material is simulated by means of a Gradient Enhanced Damage model.
