Outline of Final Research Achievements |
Theoretical, Analytical and experimental studies were done to understand possible mechanisms of practical compressive strength of carbon fiber reinforced composite (CFRP) laminates. The theoretical solution is derived to see the stress and displacement field based on the complex stress function method. Finite element analysis considering the damage accumulation and non-elastic constitutive relation was performed. Specimens having an elliptical hole or edge notch were tested to evaluate the effect of the stress concentration and dimensions of notch edge radius on the compressive strength.
