利用静电类比，我们表明，一组刚性粒子嵌入在幻影聚合物网络之间的弹性力可以表示为一个简单的珠和弹簧模型。珠子代表颗粒，弹簧代表橡胶基体.该模型是通过蒙特卡罗模拟填充硬球颗粒的橡胶，在0.1和0.3之间的体积分数进行验证。在单轴拉伸下，我们推导出了模量和全应力-应变曲线。该模型再现和扩展了以前的理论结果，所谓的水动力加固效果。
Exploiting an electrostatic analogy, we show that the elastic forces between a set of rigid particles embedded in a phantom polymer network can be represented by a simple bead-and-spring model. The beads represent the particles and the springs the rubber matrix. The model is validated by Monte Carlo simulation of rubbers filled with hard spherical particles, at volume fractions between 0.1 and 0.3. We derive both the moduli and the full stress–strain curves, under uniaxial elongation. The model reproduces and extends previous theoretical results on the so-called hydrodynamic reinforcement effect.
