摘要: 基于两球相互作用的近似解,提出了一种解析方法来预测颗粒增强复合材料的线性有效介电性质,该方法可以应用于颗粒体积分数较高(可达50%)的情况.利用割线方法还研究了该类复合材料的非线性有效性质.结果表明当外加电场较弱时该文提出的方法与Stroud和Hui的方法比较接近,当外场较强时与Yu和Hui的方法一致.Abstract: An analytical method was proposed to calculate effective linear and nonlinear dielectric properties for particulate composites.The method is based on an approximate solution of two-particle interaction problem,and it can be applied to relatively high volume concentration of particles (upto 50%).Nonlinear dielectric property was also examined by means of secant method.It is found that for low applied electric filed the propose dmethod is close to Stroud and Hui's method and for high applied electric filed it is close to Yu.s method.
