    • Crack propagation monitoring using an image deformation approach 

      Dias-da-Costa, D.; Valença, J.; Julio, E.; Araujo, H.
      Published 2017-01-01
      An image deformation method is herein proposed to monitor the crack propagation in structures. The proposed approach is based on a computational algorithm that uses displacements measured by photogrammetry or image correlation ...

    • Influence of concrete strength and steel fibre geometry on the fibre/matrix interface 

      Simões, T.; Octávio, C.; Valença, J.; Costa, H.; Dias-da-Costa, D.; Júlio, E.
      Published 2017-01-01
      The main objective of the research described in this paper was to evaluate how the concrete compressive strength and the geometry of the steel fibres influence the behaviour of the fibre/matrix interface. With this aim, ...
