对涉及粉末的过程进行建模时，需要考虑到所涉及材料的颗粒性质。离散单元法(DEM)非常适合于这一任务。它允许根据每个粒子之间产生的接触力来计算一组粒子的宏观行为。颗粒重排，这是粉末材料的一个重要标志，被明确考虑在内。我们表明，DEM在理解缺陷形成和初始微结构之间的联系方面具有明显的用途和巨大的潜力。我们提供了自由和约束烧结的各种应用实例。(C)2016年日本陶瓷学会。版权所有。
The modelling of processes involving powder needs taking into account the particulate nature of the materials involved. The Discrete Element Method (DEM) is well suited for this task. It allows the macroscopic behavior of an assembly of particles to be calculated from the contact forces generated between each particle. Particle rearrangement, a significant signature of powder materials, is explicitly taken into account. We show that DEM has demonstrated use and significant potential for understanding the link between defect formation and initial microstructure. We present diverse examples of application on free and constrained sintering. (C) 2016 The Ceramic Society of Japan. All rights reserved.
