| Outline of Final Research Achievements |
In this study, a multiscale inelastic damage development analysis method for CFRP laminates taking into account damage development behavior at microscopic interfaces was developed to evaluate failure or fracture of CFRP structures accurately. Continuum damage mechanics and an elasto-viscoplastic constitutive equation with a damage variable were introduced into the homogenization theory for time-dependent composites. Using the present analysis method, the damage development behavior at the microscopic interfaces and decrease of macroscopic mechanical properties of the CFRP laminates were analyzed simultaneously.
