Modelling of basic creep effect on concrete damage at a mesoscale level
Abstract
In its service-life concrete is loaded and delayed strains appear due to creep phenomenon. Some theories suggest that micro-cracks nucleate and grow up when concrete is submitted to a high sustained loading, which contribute to make the concrete weaker. Thus, it is important to understand the interaction between the viscoelastic deformation and damage in order to design reliable civil engineering structures. Several creep-damage theoretical models have been proposed in the literature. However most of these models are based on empirical relations applied at the macroscopic scale. Coupling between creep and damage is mostly realised by adding some parameters to take into account the microstructure effects. In the author opinion, the microstructure effects can be modelled by taking into account the effective interactions between the concrete matrix and the inclusions. In this paper, a viscoelastic model is combined with an isotropic damage model. The material volume is modelled by a Digital Concrete model which takes into account the "real" aggregate size distribution of concrete. The results show that stresses are induced by strain incompatibilities between the matrix and aggregates at mesoscale under creep and lead to cracking.
