Thermo-mechanical properties of polymer nanocomposites reinforced with randomly distributed silica nanoparticles- Micromechanical analysis

A three-dimensional micromechanics-based analytical model is developed to study thermo-mechanical properties of polymer composites reinforced with randomly distributed silica nanoparticles. Two important factors in nanocomposites modeling using micromechanical models are nanoparticle arrangement in matrix and interphase effects. In order to study these cases, representative volume element (RVE)...

COMPARISON OF MECHANICAL AND ELECTRICAL PROPERTIES OF PIEZOELECTRIC COMPOSITES PZT/ZnO AND PZT/Al FABRICATED BY POWDER METALLURGY

Lead zirconate titanate (PZT) as a piezoelectric ceramic has been used widely in the fields of electronics, biomedical engineering, mechatronics and thermoelectric. Although, the electrical properties of PZT ceramics is a major considerable, but the mechanical properties such as fracture strength and toughness should be improved for many applications. In this study, lead monoxide, zirconium ...

Computational Micromechanics of Particle-reinforced Composites: Effect of Complex Three-dimensional Microstructures

It is of interest to incorporate quantitative characterization of actual three-dimensional microstructures in micromechanical analysis of composites due to the dominant influence of microstructural features on the material behavior. In this paper, a methodology has been developed to perform finite element-based simulations on complex three-dimensional microstructures, through its application to...

Cohesive modeling of dewetting in particulate composites: micromechanics vs. multiscale finite element analysis

The effect of damage due to particle debonding on the constitutive response of highly filled composites is investigated using two multiscale homogenization schemes: one based on a closed-form micromechanics solution, and the other on the finite element implementation of the mathematical theory of homogenization. In both cases, the particle debonding process is modeled using a bilinear cohesive ...
