周期性边界条件下炭黑增强橡胶基复合材料有效弹性性能数值模拟
Numerical simulation for effective elastic behavior of carbon black filler particle reinforced rubber matrix composites based on periodic boundary conditions
摘要
Abstract
Based on periodic boundary conditions, representative volume element with random distribution pattern has been established and applied to study and analyze the macromechanical properties of the carbon black filled rubber composites by the micromechanical finite element method. The deformation and stress field for composites in the models with circle and square carbon black filler particles respectively. and the dependence of the effective elastic modulus of the composites on particle volume fraction have been investigated and discussed. Simulation results indicate that the modulus of the composite is increased considerably with the introduction of carbon black filler particles, and the effective elastic modulus of the composite is increased with the increase of the particle volume fraction. And with the same filler content, it is obvious that the models with square carbon black particles generate higher predictions on the effective modulus of the composite than the models with circle particles.关键词
