Numerical simulation of the effects of volume fraction, aspect ratio and fibre length distribution on the elastic and thermoelastic properties of short fibre composites

Evaluation of influence of interphase material parameters on effective material properties of three phase composites

“…The effective material properties of two phase randomly distributed fiber and particle reinforced composites are extensively studied by using analytical and numerical analysis [1][2][3][4][5][6][7][8]. Pagano and Tandon [9,10] approximate the effective properties of thermoelastic composites with coated fibers using unit cell approach.…”

“…The main idea of the method for modeling RVE to represent a real composite behavior is to find a globally homogeneous medium equivalent to the original composite, where the strain energy stored in both systems is approximately the same. 10) As pointed out by several researchers, [9][10][11][12] a RVE should be typical of the whole composite microstructure and contains a sufficient number of inclusions for the apparent overall properties to be effectively independent of the boundary condition. In this point of view, this study focused on the statistical homogeneity of the effective elastic modulus (Young's modulus) of the model to be statistically representative of the composite.…”

“…Therefore, the finite element method (FEM) has been extensively employed to determine the effective material properties of short fiber and particle reinforced composites. [7][8][9][10][11][12] Numerous studies have been reported on the effective modulus and overall stressstrain responses of these composites using representative unit cell 7,8) and 2D/3D microstructure [9][10][11][12] models. Most of these models were constructed using representative volume elements (RVEs), which were selected to reflect the actual microstructures of the composite.…”

“…Most of these models were constructed using representative volume elements (RVEs), which were selected to reflect the actual microstructures of the composite. Recently, Gusev et al 9) developed a Monte Carlo 13) based simulation for an aligned fiber reinforced composite, in which the actual distributions of the fiber aspect ratio were fully represented by 100 nonoverlapping fibers. Kari et al 10) employed FE analysis to investigate the effect of the volume fraction and fiber aspect ratio on a random short SiC fiber reinforced metal matrix composite (MMC).…”

Entropy Production of Composites with Elliptical Inclusions for Bone Analysis

“…They propose that their method can be applied to any number of phases and there are no restriction regarding the number of materials, geometry and material symmetry and this can be used effectively to determine material coefficients of different types of fiber and particle reinforced composites. In addition, Gusev et al 7,8 experimented with randomly distributed short fiber composites and compared them with numerical results; he restricted his investigation to lower volume fractions of particles.…”
