扩展了基于颗粒的模拟方法，使用离散元法（DEM）来模拟固态烧结，以考虑变量配位数。该模型适用于配位数不同但绿密度相似的绿粒子组态。对于单尺寸粒子和具有尺寸分布的粒子，初始配位数的降低都强烈地延缓了致密化。这一观察结果与所选择的绿色密度无关。
A particle-based simulation approach using the discrete element method (DEM) to simulate solid-state sintering is extended in order to account for variable coordination numbers. The model is applied to green particle configurations with different coordination numbers, but similar green densities. For configurations both with monosized particles and with particles having a size distribution it is shown that a decrease in initial coordination number strongly retards densification. This observation is independent of the selected green density.
