“…The results presented are an improvement when compared to previous work [33]. Other similar models correlating matrix cracking and stiffness loss were subsequently developed by El-Mahi et al [35], Smith and Ogin [36] and Katerelos et al [37]. Moreover, Reifsnider [38] proposed a critical element method to correlate stiffness and residual strength degradation with damage mechanisms in unidirectional composites.…”

Abstract. Due to the increased use of composite materials in the aerospace industry, numerous attempts have been made to develop fatigue models in order to predict the fatigue behaviour and consequently the fatigue life of these materials. Existing fatigue models have significant deficiencies, thus are not widely acceptable in the industry. A better understanding of the exhibited fatigue behaviour of composite materials is consequently required. The complex nature of fatigue behaviour in fiber-reinforced composite materials is presently investigated. An explicit progressive damage model, that is mechanistic in nature, is currently being developed using the concept of a representative volume element. A micromechanical finite element model that is capable of explicit damage initiation and propagation modeling is utilized for simulation of damage development. The predicted numerical results illustrate the capabilities of the current model. Future work is also outlined in the paper as the development of the fatigue model is continued.

“…The basic premise is that the Raman vibrational wave numbers of certain chemical groups of commercial reinforcing fibers, such as aramid or carbon, are dependent on the stress and strain levels. The methodology has been shown to work well for measuring evolution of ply cracking damage and resulting stiffness property changes, as reported in Katerelos, Lundmark, Varna, and Galiotis (2007), Katerelos, Kashtalyan, Soutis, and Galiotis (2008), and Katerelos, Varna, and Galiotis (2008).…”

“…Damage mechanisms and damage accumulation in cross-ply composite laminates under quasi-static and fatigue loading have been the subject of many investigations, most recently in [1][2][3][4][5][6][7][8]. However, multilayer damage of cross-ply laminates has been very little modelled theoretically or simulated numerically (by means of finite elements), mainly because the analysis of a representative segment defined by intersecting pairs of cracks is very cumbersome.…”

In this paper, the Equivalent Constraint Model (ECM) together with a 2-D shear lag stress analysis approach is applied to predict residual stiffness properties of polymer and ceramic matrix [0/90 n /0] cross-ply laminates subjected to in-plane biaxial loading and damaged by transverse and longitudinal matrix cracks. It is found that the longitudinal Young's modulus, shear modulus and major Poisson's ratio undergo large degradation as the matrix crack density increases, with Poisson's ratio appearing to be the most affected by transverse cracking. In cross-ply laminates with thick 90°layer strip-shaped delaminations begin to initiate and grow from the tips of matrix cracks at the 0°/90°interface. These delaminations contribute to further stiffness degradation of such laminates, and hence have to be taken into account in failure analysis models. The thickness of the 90°layer plays an important role; the thicker the 90°layer, the bigger stiffness reduction suggesting a size (volume) effect at ply level. In SiC/CAS cross-ply laminates reduction in the longitudinal modulus occurs mainly due to transverse cracks, while the shear modulus appears to be the most affected by the presence of longitudinal cracks. The shear modulus reduction ratio predicted previously by a semi-empirical formula is, in the most of cases, within 10% of the current ECM/2-D shear lag approach value. In some cases, though, the error of the semiempirical finite element expression can be as big as 20% since it fails to capture damage mode interaction.
