“…On the other hand, the fiber breakage failure is assumed if the longitudinal stress of the fiber attains its tensile strength. To make the formula applicable when a fiber end debonding occurs, incorporation of the Shear-Lag formula with an equivalent inclusion method was proposed (Jain et al., 2015), wherein the fiber and the matrix stress levels and the shear stress in between them are given (Despringre et al., 2016; Jain et al., 2015; Sun et al., 2015).…”

This work deals with the fiber ends debonding-induced elastic moduli degradation of a short fiber reinforced composite (SFRC). The strain fields of the matrix in a representative volume element (RVE) of the SFRC are determined from an imaginary fiber technique. By using the debonding boundary conditions, the debonded modulus of the composite is derived, which is affected by not only the far-field but also the transient solutions for the longitudinal strain of the matrix. Particularly, the imaginary fiber technique provides unbounded solution for a moderately large fiber aspect ratio. This is resolved by separating the RVE along the fiber direction into two domains. Combining the longitudinal strains in both domains, the longitudinal modulus is determined, and the longitudinal bridging tensor element in the micromechanics Bridging Model is amended. Five elastic moduli of an SFRC after the fiber end debonding are obtained on the amended Bridging Model. The effects of the fiber volume fraction, fiber aspect ratio, and fiber-to-matrix modulus ratio on the end-debonded longitudinal modulus, transverse modulus, and longitudinal Poisson’s ratio are investigated.
