文摘
- •
An upper limit of dynamic strain on macro fiber composite (MFC) for achieving reliable performance is obtained experimentally.
- •
MFC shows high reliable performance for 60 million cycles below dynamic strain amplitude of 600 μϵ.
- •
A significant degradation in performance of MFC is noticed when operating above 1000 μϵ of strain amplitude.
- •
MFC shows nonlinear stress-strain behaviour below 1000 μϵ and does not exhibit clear linear elastic limit.
- •
Cracking is initiated in MFC around 1000 μϵ during tensile testing.
