Abstract

This paper presents a simple application of continuum damage modelling to failure analysis. An isotropic damage model is described and its non local enhancement discussed. The calibration of the model parameters is addressed with the help of structural size effect data. Such a size effect is a feature of non local models and is also observed experimentally. We show that this scaling law of fracture can be a convenient tool for the purpose of model calibration, and in particular for the determination of the internal length which is introduced in non local models.
