Abstract

The article substantiates the main possibilities of filling with irregular bodies, and provides a visual analysis of the parameters formed as a result of structures. It was found out that the form factor acts as the main indicator of the characteristic parameter of changes in the structure and all other parameters of an inhomogeneous medium. It was also found out that when filling a container with irregular ellipsoid elements, the conditions for non-opening (one-way contact) must be met. The obtained calculations of the form factor show the minimum value of the average coordination number of an inhomogeneous medium. This allows us to assert and predict reliable modelling results (± 2-3%). It is also important that the developed simulation model for modelling an inhomogeneous medium using an irregular (ellipsoid) shape of elements can significantly reduce the time spent on conducting field experiments, as well as simulate irregular elements with different shape factors.

含椭圆异形元的非均匀介质的计算机模拟

本文论证了不规则体填充的主要可能性，并对结构所形成的参数进行了直观分析。研究发现，形状因子是反映非均匀介质结构变化特征参数及其他参数的主要指标。还发现，在填充不规则椭球元容器时，必须满足非开启(单向接触)条件。所得的形状因子计算结果显示了非均匀介质的平均配位数的最小值。这使我们能够断言和预测可靠的建模结果(±2-3%)。同样重要的是，所开发的使用不规则(椭球)形状元素模拟非均匀介质的模拟模型可以显着减少进行现场实验所花费的时间，并且可以模拟具有不同形状因素的不规则元素。

期刊介绍： Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
