“…However, the influence of reinforcement/matrix interface on material properties is difficult to characterize using normal experimental methods due to its small size, complicated chemical compositions and microstructures, and mechanical environment, etc. Finite element simulation method provides a new approach to analyze the interface properties, such as Wang and Jasiuk [9] and Jiang et al [10] investigated the effects of transition interface modulus and Poisson's ratio on the composites properties and the results show that, the composites properties were more dependent on the modulus. In 2012, our team proposed a unit cell model with transition interfaces to analyze the interface properties and found that the strength and thickness of transition interface have large impacts on composites ductility.…”

A systematic simulation has been carried out using finite element method to investigate the effects of particle/matrix transition interface on the stress distributions in YAl 2 particle reinforced Mg-Li-Al composites. The results show that the transition interface could improve the continuity of physical properties between particles and matrix, thus enhancing the stress transfer efficiency. Meanwhile, the transition interface can also reduce the degree of stress concentration at interface, resulting in higher strength and toughness of composites.

“…Phani and Sanyal (2008) used the Mori-Tanaka mean-field approach to derive a relation between the shear modulus and Young's modulus of isotropic porous ceramics. Jiang et al (2008) performed numerical studies on the effective shear modulus of particle-reinforced composites with an inhomogeneous inter-phase. Scarpa and Tomlin (2000) used numerical simulations to determine the transverse shear modulus of in-plane negative Poisson's ratio honeycombs.…”

The effect of various offaxis angles and lamina material properties on the shear modulus and the stress distribution of a circular cutout in an orthotropic composite plate under shear loadings are presented. Based on the generalized Hooke's law, the generalized plane stress condition and the complex variable method, a dimensionless analysis is used to evaluate the influence of various elastic moduli E 1 , E 2 , G 12 and ν 12 on the laminate shear modulus and the stress distribution along the boundary of the circular cutout within the laminate under shear loading. The results obtained from this dimensionless analysis provide a set of general design guidelines for structural laminates with high-precision requirements in engineering applications.

“…Since most of the existing FEM analysis for the debonding damage are carried on a unit cell model, so a big obstacle in the process of comparing the predictions of damage variables with numerical results is the absence of appropriate equivalent medium model. Fortunately, Jiang et al presented a new micromechanics model for PRC with regularly distributed particles (7)- (9) . Under these necessary conditions, the validity of these available damage variables can be examined.…”

This paper is to study the impact of partially-debonding damage on the effective elasticity of particle reinforced composites (PRC). The particles would lose a part of load-carrying capacity after the interface partially-debonding happens. The damage degree is determined by damage variable parameters in terms of the debonding angle. Two sets of prevailing definitions of damage variable parameters, i.e. Zhao's and Liu's, are verified by finite element method (FEM), and the deficiencies of them are clearly demonstrated. To better characterize the effect of the partially-debonding damage, damage variables proposed by Wada are incorporated into an explicit micromechanics model to predict the effective properties of PRC. Finally, the accuracy and efficiency of the developed method are confirmed. In order to deeply understand the inherent damage mechanism, FEM is utilized to analyze the specific stress distribution in and around a debonded particle, and the evolution of the average particle stress with the debonding angle is revealed.
