Highly Predictive Structural Cell for Particulate Polymeric Composites

Abstract

A unit cell of a specified shape under specified loading conditions has been offered for predicting some basic properties of particulate polymeric composites. The stress-strain state of the bonded and debonded cell has been calculated in the framework of the large deformation approach within a wide range of filler volume concentrations. Effective modulus-filler concentration curves have been predicted on the basis of the unique cell investigation for bonded and debonded cell states and have proved to be in good agreement with the available experimental data. Local strain concentration as a function of cell extension and filler volume loading has been estimated.

Prediction for debonding damage process of glass beads-reinforced modified polyphenylene oxide under simple shear

“…A number of finite element analyses have been conducted for predicting the elastic properties of PPC [1,[9][10][11][12][13] subject to tension or compression. Particle-matrix debonding in PPC subject to tension has been simulated by Moshev and Kozhevnikova [14,15], and Fan et al [16] using the two-dimensional cylindrical axisymmetric unit cell model. However, these two-dimensional axisymmetric cells are not actual repetitive unit but are related in their dimensions to the interparticle spacings.…”
