摘要: Abstract A constitutive framework is developed for the inelastic analysis of composite structures. It based on a Continuum Damage Mechanics approach, at mesoscopic level each ply (for laminates) or macroscopic more homogeneous sequences. The theory in hierarchical order, involving successive modelling elasticity coupled with damage, elastoviscoplasticity damage and viscoelasticity/recovery damage. particular attention focused deactivation effects, which stays key difficulty cyclic loadings. capabilities models are illustrated three quite different materials, SiC/SiC composite, SiC/Ti C/PMR15 composite.
