为了建立陶瓷粉末压实的预测模型，我们研究了表征陶瓷粉末压实密度梯度的方法，回顾和比较了现有的压实模型，对喷雾干燥的氧化铝粉末进行了压实实验，并对模型颗粒材料进行了力学测试和压实实验。模具填充和颗粒填充以及单个颗粒的行为在确定压实行为方面起着重要作用，应纳入现实的压实模型。这些结果支持使用离散元素建模技术和统计力学原理来开发压缩的综合模型，这应该可以通过具有并行处理能力的计算机实现。
With the objective of developing a predictive model for ceramic powder compaction we have investigated methods for characterizing density gradients in ceramic powder compacts, reviewed and compared existing compaction models, conducted compaction experiments on a spray dried alumina powder, and conducted mechanical tests and compaction experiments on model granular materials. Die filling and particle packing, and the behavior of individual granules play an important role in determining compaction behavior and should be incorporated into realistic compaction models. These results support the use of discrete element modeling techniques and statistical mechanics principals to develop a comprehensive model for compaction, something that should be achievable with computers with parallel processing capabilities.
