 Abstract

In this paper the anisotropic behavior of ASR swelling is simulated through a 1D smeared crack model. The choice of the engineering properties is discussed, in particular for the evolution of the tensile strength and the Young’s modulus during the swelling. The last one is used as the main indicator for ASRrelated damage. The model is hampered by the lack of experimented data available in literature. The outlook of the approach is that orthotropic stiffness degradation could be used to explain anisotropic swelling.
