- •
The hysteresis loops models have been developed based on the Coulomb friction law instead of a constant frictional shear stress usually assumed in hysteresis analysis.
- •
Based on the damage mechanism of fiber slipping relative to matrix, the interface slip lengths are obtained by the fracture mechanics approach.
- •
The effects of matrix stochastic cracking, fiber volume fraction, interface properties and fiber Poisson ratio on hysteresis loops, interface slip lengths and interface slip stresses have been analyzed.
