“…Micromechanical damage models for composites considering interfacial debonding were proposed by many researchers (e.g., Zhao and Weng, 1997;Lee, 2000, 2001;Lee, 2001;Liang et al, 2006;Liu et al, 2006;Lee and Kim, 2007). They replaced the isotropic debonded inclusions by the perfectly debonded inclusions with yet unknown transversely isotropic properties to describe the loss of the load-transfer capacity of debonded interface between inclusion and matrix.…”

A micromechanical framework is proposed to predict the effective elastic behavior and weakened interface evolution of particulate composites. The Eshelby's tensor for an ellipsoidal inclusion with slightly weakened interface [Qu, J., 1993a. Eshelby tensor for an elastic inclusion with slightly weakened interfaces. Journal of Applied Mechanics 60 (4), 1048-1050; Qu, J., 1993b. The effect of slightly weakened interfaces on the overall elastic properties of composite materials. Mechanics of Materials 14, 269-281] is adopted to model spherical particles having imperfect interfaces in the composites and is incorporated into the micromechanical framework. Based on the Eshelby's micromechanics, the effective elastic moduli of three-phase particulate composites are derived. A damage model is subsequently considered in accordance with the Weibull's probabilistic function to characterize the varying probability of evolution of weakened interface between the inclusion and the matrix. The proposed micromechanical elastic damage model is applied to the uniaxial, biaxial and triaxial tensile loadings to predict the various stress-strain responses. Comparisons between the present predictions with other numerical and analytical predictions and available experimental data are conducted to assess the potential of the present framework.

“…Many micromechanical models incorporating damage mechanisms have been developed in order to obtain the homogenized elastic properties of composite materials (Qu, 1993a,b, Tohgo andWeng, 1994;Zhao and Weng, 1995, 1997Ju and Lee, 2001;Liu et al, 2004Liu et al, , 2006Pyo, 2007, 2008b; Pyo and Lee, 2009) and/or to study the effect of microcracks on the elastic behavior of brittle solids (Karihaloo and Fu, 1989;Lee and Liang, 2004;Lee and Simunovic, 2006;Lee and Pyo, 2009). Many finite element (FE) analyses of damage and failure in laminated composites under various loading cases have also been carried out (Davalos et al, 1996;Luciano and Zinno, 2000;Maa and Cheng, 2002;Basu et al, 2003;Kilic and Haj-Ali, 2003;Rodriguez and Ochoa, 2004;Liang et al, 2006;Guo, 2007;Lee and Kim, 2007;Maimi et al, 2007;Teng, 2007;Rudraraju et al, 2008).…”

a b s t r a c tBased on the micromechanics-based constitutive model, derived in our preceding work . A 3D-damage model for fiber-reinforced brittle composites with microcracks and imperfect , incorporating a multi-level damage model and a continuum damage model, the overall elastic behavior and damage evolution of laminated composite structures are studied in detail. The constitutive model is implemented into the finite element program ABAQUS using a user-subroutine UMAT to solve boundary value problems of the composite structures. The validity of the implemented constitutive model is assured by comparing the predicted stress-strain curves with experimental data available in literature under uniaxial tension with various fiber orientations. The results show that the proposed micromechanics-based constitutive model accurately predict the overall elastic-damage behavior of laminated composite structures having different material compositions, thicknesses and boundary conditions.

“…It is assumed that all of the particles are perfectly bonded in the initial state, but some of the particles are damaged by increasing loading or deformation on the composites, and those particles could be then separately regarded as damaged particles (completely debonded particles, phase 2) that may lose their load-carrying capacity. The effective elastic constitutive equation of the particle-reinforced composites has been studied by many researchers [32][33][34][35][36][37][38]. In particular, following the ensemble-averaged volume method proposed by Ju and Chen [23,24], the effective elastic tensor C * of the three-phase composites can be given by…”

The objective of this study is to develop a micromechanics-based viscoelastic damage model that can predict the overall viscoelastic behavior of particle-reinforced polymeric composites undergoing damage. The emphasis here is that the present model successfully combines a rate-dependent viscoelastic constitutive model and a damage model. The Laplace transform based on the Boltzmann superposition principle and the ensemble-volume averaged method suggested by Ju and Chen (Acta Mech 103:103-121, 1994a; Acta Mech 103:123-144, 1994b) are extended toward effective viscoelastic properties. Further, the probability of the distribution function of Weibull (J Appl Mech 18:293-297, 1951) is adopted to describe a damage model that is dependent on damage parameters. A series of numerical simulations including parametric studies, and experimental comparisons are carried out to give insight into the potential capacity of the present micromechanics-based viscoelastic damage framework.
