Particulate Composite Materials: Numerical Modelling of Cross-linked Polymer Reinforced by Alumina Based Particles

Popis výsledku v původním jazyce

The contribution deals with an estimation of macroscopic mechanical properties of a particulate composite under uniaxial tensile loading. Composite studied consists of polymer matrix in a rubbery state (polymethylmethacrylate - PMMA) and alumina based particles (Al2O3). Numerical modelling based on the finite element method (FEM) was performed to determine stress-strain behaviour of the particulate composite. Numerical simulations took into account hyperelastic properties of cross-linked polymer matrix,described by the three parameter Mooney-Rivlin material model. Representative volume element (RVE) model was chosen for FE analyses as an approach modelling a microstructure of the composite. Various compositions of particles, their different shape andorientation have been considered in the study. Various directions of loading of RVE have also been investigated. The progressive damage model has been implemented into the numerical models. Mechanical properties obtained from computations
