Adhesion phenomena across interfaces with spatially heterogeneous adhesive properties

Project Description

The project aims to explore the effect of heterogeneities on the mechanical behavior of bonded interfaces through integrated experiments and simulations. The research seeks to systematically design multiple sites of potential crack pinning across the interface, able to trigger sequential events of initiation, propagation and crack arrest, thus promoting macroscopic variations of strength and toughness. Inspiration in the search for such novel material configurations is derived from those observed in nature. Successful design of these bio-inspired interfaces can lead to quite interesting technological applications.​​​​​​

Gilles Lubineau
Professor Lubineau’s research simultaneously involves computational, modeling and experimental developments to tackle complex problems related to composite engineering and more generally to heterogeneous materials. 

Lubineau’s research is focused on four key areas:
  • Integrity of composite materials and structures. Isotropic and anisotropic damage theories; fracture mechanics; homogenization techniques bridging micro-mechanical models to meso/macro-scale models; multi-scale modeling; and damage mechanisms in nano-reinforced multiscale composites.
  • Durability of composite materials and structures; modeling of aging for polymer-based CFRPs under various environments (moisture, temperature, radiation, oxidation, mechanical fatigue); aging of steel pipes in sour environments; and the development of multiphysics-related models (experimental, modeling and computational work).
  • Inverse problems for the identification of constitutive parameters; digital image correlation-based identification techniques; identification techniques for interfaces in joints and laminates; and identification techniques based on 2-D (optical pictures) and 3-D (tomography) image correlation.
  • Multiscale coupling techniques; coupling between non-local continuum and local continuum models; and upscaling strategies for handling localized effects in large-scale simulations.
