Abstract

Constitutive modelling in geotechnical engineering and applied earth sciences is facing the challenge of assessing the long-term potential of both man-made and natural geohazards. This involves designing engineering operations for length scales and timescales well beyond those observable in the laboratory. In order to bridge the gap between scales, study rock behaviours well beyond their yield point and provide predictive capabilities to long term problems, constitutive models need to be equipped with multi-physical information that can be measured at laboratory time-scales and extrapolated beyond them. Enriching constitutive models with a su...  more
