To describe many-particle systems suspended in incompressible low-Reynolds-number fluids, effective hydrodynamic interactions can be introduced. Here, we consider particles embedded in elastic media. The effective elastic interactions between spherical particles are calculated analytically, inspired by the approach in the fluid case. Our experiments on interacting magnetic particles confirm the theory. In view of the huge success of the method in hydrodynamics, we similarly expect many future applications in the elastic case, e.g., for elastic composite materials.
为了描述悬浮在不可压缩低雷诺数流体中的多粒子系统，可以引入有效的流体动力学相互作用。在这里，我们考虑嵌入弹性介质中的粒子。受流体情形中方法的启发，解析计算了球形粒子之间的有效弹性相互作用。我们对相互作用磁性粒子的实验证实了该理论。鉴于该方法在流体动力学方面取得的巨大成功，我们同样期望它在弹性情形中有许多未来应用，例如用于弹性复合材料。
