Multi-scale modelling of materials is now widely spread as it allows for a comprehensive analysis of their behaviour. The idea of this paper is to propose a methodology that couples Digital Images Correlation with multi-scale numerical simulations in order to identify a material behaviour that is too complex to obtain at the observation scale but that can be described in a simpler way at a ﬁner scale. For this purpose, a Mechanical Image Correlation approach is proposed that involves a multi-scale numerical model. The capabilities of the proposed method is illustrated based on an example dedicated to the identiﬁcation of heterogeneous orthotropic elastic properties of softwood.
