Abstract

Marine renewable energy and naval structures are subjected to severe environmental conditions (seawater or humid air) and continuous mechanical loadings. These factors are reducing the lifetime of these structures by accelerating the damage development. However, at the current state, there is no predictive model taking account of the coupled phenomena.

OBJECTIVES

  • Understand the coupling between the two physical phenomena: diffusion & mechanical behaviour
  • Perform creep tests in specific environment (humid air / immersion)
  • Develop numerical models to simulate this coupling
