“…Instead, following [16], we consider the non-linear contact problem where the matrix-fiber interaction is described by the cohesive zone model (CZM). Specifically, we adopt the bi-linear CZM of interface in the form suggested by Alfano and Crisfield [24].…”

“…There, a simple model of progressive debonding has been proposed where the peak interface normal stress was assumed to be responsible for the interface crack onset. In the numerical approach [16], the micromechanical model of interface debonding in FRC has been developed. There, simulation of progressive debonding in fiber reinforced composite has been performed based on the multiple fiber-matrix contact problem with CZM option.…”

“…Han et al (2006) used a softening decohesion model to study the initiation and propagation of debonds in several single and two fibre configurations using the boundary element method (BEM). Recently, Ngo et al (2010) used a new potential-based CZM to study the inclusion-matrix debonding in an integrated approach involving micromechanics, and Kushch et al (2011) used a bi-linear CZM to simulate progressive debonding in multi-fibre models for a composite showing the formation of debond clusters.…”

A linear elastic-brittle interface model: application for the onset and propagation of a fibre-matrix interface crack under biaxial transverse loads

A new linear elastic and perfectly brittle interface model for mixed mode is presented and analysed. In this model, the interface is represented by a continuous distribution of springs which simulates the presence of a thin elastic layer. The constitutive law for the continuous distribution of normal and tangential initially-linear-elastic springs takes into account possible frictionless elastic contact between adherents once a portion of the interface is broken. A perfectly brittle failure criterion is employed for the springs, which enables the study of crack onset and propagation. This interface failure criterion takes into account the variation of the interface fracture toughness with the fracture mode mixity. A unified way to represent several phenomenological both energy and stress based failure criteria is introduced. A proof relating the energy release rate and tractions at an interface point (not necessarily a crack tip point) is introduced for this interface model by adapting Irwin's crack closure technique for the first time. The main advantages of the present interface model are its simplicity, robustness and computational efficiency, even in the presence of snap-back and snap-through instabilities, when the so-called sequentially linear (elastic) analysis is applied. This model is applied here in order to study crack onset and propagation at the fibre-matrix interface in a composite under tensile/compressive remote biaxial transverse loads. Firstly, this model is used to obtain analytical predictions about interface crack onset, while investigating a single fibre embedded in a matrix which is subjected to uniform remote transverse loads. Then, numerical results provided by a 2D boundary element analysis show that a fibre-matrix interface failure is initiated by the onset of a finite debond in the neighbourhood of the interface point where the failure criterion is first reached (under increasing proportional load); this debond further propagates along the interface in mixed mode or even, in some configurations, with the crack tip under compression. The analytical predictions of the debond onset position and associated critical load are used for several parametric studies of the influence of load biaxiality, fracture-mode sensitivity and brittleness number, and for checking the computational procedure implemented.

“…Debonding between the matrix and the surrounding inclusions of a composite material has been also studied in [24] by using contact mechanics and homogenization concepts. In [25,26] an interfacial failure model with normal and tangential brittle-elastic springs and a bi-linear cohesive zone model have been developed respectively, for the simulation of progressive debonding in the matrix-fiber interface of composite materials. In [27] a bilinear cohesive law is used to simulate failure between the fibers and the matrix interface; then, a comparison between periodic and minimal kinematic boundary conditions is given.…”
