Fracture Mechanics of Fiber-Matrix Interfaces in Composites under Transverse Loading

Abstract:

The Failure of the Interface between Fiber and Matrix under Transverse Loading is the Key Factor Controlling the Failure Process in Composite Materials. the Debonding Process of a Fiber within a Unidirectional Composite is Studied by Finite Element Analyses Using a Representative Volume Element. the Energy Release Rate is Calculated for Different Fiber Volume Fractions. Two Load Cases are Taken into Account, Pure Transverse Tension and Shear Loading.
