论文摘要
对于广泛的应用，我们需要对粒状物质进行DEM模拟，并需要与柔性弹性边界接触。我们提出了一种描述颗粒颗粒与柔性弹性膜之间相互作用的新方法。在这里，标准的质量弹力模型方法是由膜的三角剖分给出的表面贴片补充的。与标准的质量弹簧模型相反，我们的仿真方法即使对于较大的粒度分散体，也可以进行有效的仿真。这种新方法允许将质量弹簧系统块化，从而导致计算效率大幅提高。为三轴检验证明并测试了模拟方法。
For a wide range of applications, we need DEM simulations of granular matter in contact with flexible elastic boundaries. We present a novel method to describe the interaction between granular particles and a flexible elastic membrane. Here, the standard mass-spring model approach is supplemented by surface patches given by triangulation of the membrane. In contrast to standard mass-spring models, our simulation method allows for an efficient simulation even for large particle size dispersion. The novel method allows coarsening of the mass-spring system leading to a substantial increase in computation efficiency. The simulation method is demonstrated and benchmarked for a triaxial test.
