Research Interests

Professor Dugnani has broad interests in the field of solid mechanics, especially theoretical and experimental fracture mechanics. His current and past topics of interests include:

  • Efficient Computer Vision-based algorithms for automated fractographic analysis
  • Modeling three-dimensional, unstable fracture behavior of brittle materials
  • Modeling/analyzing the physical behavior of ion-exchanged silicate glasses
  • Structural Health Monitoring (SHM) of composite structures; damage detection and image reconstruction schemes based on surface waves propagation.
