First, a diffusive and swelling campaign was carried out with water immersion at 25°C and 60°C. Various experimental tests have also been undertaken at different stages of ageing to highlight and quantify the influence of water diffusion on elastic and viscoelastic properties. A model is then proposed to simulate the hygro-viscoelastic behaviour of the studied material through finite element simulations. A good agreement between the experimental and numerical results is observed. %G English %2 https://nantes-universite.hal.science/hal-03711552/document %2 https://nantes-universite.hal.science/hal-03711552/file/Quentin_DEZULIER_New_Revised_Paper_CompPartB_unmarked.pdf %L hal-03711552 %U https://nantes-universite.hal.science/hal-03711552 %~ CNRS %~ EC-NANTES %~ IFREMER %~ UNAM %~ GEM %~ NANTES-UNIVERSITE %~ NANTES-UNIV
