“…11, the plastic strain around the crack site increases with decreasing angle. Koyanagi et al (2014) experimentally demonstrated that the morphology of the matrix crack depends on the strain rates, and we also simulated the dependency using the unit cell. Fig.…”

“…Asp et al (1996aAsp et al ( , 1996b presented the failure process based on the dilatation energy criterion, and Okabe et al (2011) simulated the cracking strain using the periodic unit cell and modified Gurson Law. Moreover, Sato et al (2014) successfully used a combination of the dilatation energy criterion and the modified Gurson Law to predict the cracking strain of an off-axis ply. As shown in Fig.…”

This review of previous studies on the damage and mechanical modelling of fibre-reinforced composite materials, especially carbon-fibre-reinforced plastic composites, is based on the findings of recent studies conducted in conjunction with other researchers. Studies that utilized various modelling scales, ranging from macroscopic to microscopic, are considered. The modelling of impact damage, ply cracks, ultimate tensile failure, the initiation of transverse ply cracks, the micro-mechanical properties of interfaces and molecular dynamics are specifically addressed. In addition, the scope for future work in the field is described.

“…Tabiei et al [19][20][21][22] developed a finite element method to consider the nonlinearity and dynamic sensitivity in calculating mechanical properties of fibrous composites by using the Goldberg model for polymers [25]. Koyanagi et al [26] studied the strain rate dependent transverse tensile of UD composites numerically. Although the fiber, matrix and interface have been modeled individually, but the aim of their study was investigating the failure modes of UD composites under strain rate dependent transverse tensile loadings.…”

“…In particular, intralaminar failure, including matrix failure and interfacial debonding, or interlaminar failure between neighboring laminae is more important than the final failure that comes with fiber breakage in CFRP structures under operation. Initiation and progress of transverse cracks, which are the main initial failure modes of CFRP laminates, have been analyzed by considering matrix failure and interfacial debonding (Okabe et al, 2011(Okabe et al, , 2015Koyanagi et al, 2014). It has been reported that such transverse crack tends to occur in a relatively low stress level and is strongly affected by interfacial properties between carbon fibers and a matrix resin.…”

In this study, the damage-development behavior of carbon fiber-reinforced plastic (CFRP) laminates considering the nonlinear mechanical properties of a matrix resin was investigated through a numerical simulation based on a homogenization theory and continuum damage mechanics. A scalar damage variable was applied to elastoviscoplastic constitutive equations, following which, the constitutive equations were introduced into the homogenization theory for elasto-viscoplastic materials. Uniaxial tensile tests including unloading and reloading phases under several strain rates were performed using a specimen made of an epoxy resin. The damage-development behavior of the unidirectional CFRP laminates was then analyzed using the homogenization theory. From the numerical results, viscoplastic behavior was observed in the stress-strain curves, and the stress decreased drastically as the damage of the epoxy resin developed. The microscopic distributions showed that the failure initiated at the epoxy resin around the fibers arranged along the loading direction and progressed by connecting the high damage variable regions of the epoxy resin. Uniaxial tensile tests of the unidirectional CFRP laminates were also performed to validate the numerical results. The experimental fracture stresses were distributed between the maximum and minimum stresses at the failure starting points obtained from the numerical results. Thus, it was confirmed that the proposed numerical method could analyze the damage-development behavior of CFRP laminates.
