Composites Science and Technology, Elsevier, 2006, 66 (3-4), pp.397-406. ⟨10.1016/j.compscitech.2005.07.019⟩

International audience; The aim of this work is to propose an analytical model for transient hygro-elastic stresses in transversely isotropic multi-layered cylinders. This approach allows one to calculate the time and space dependent hygro-elastic st

International audience; The development of thermal residual stresses was investigated in polycrystalline materials. Two complementary ways were used: the experimental values obtained by X-ray diffraction were compared to the results predicted by self
