摘要
介绍了焊接熔池组织模拟的GBE模型。此模型是通过计算相邻晶粒间晶界的位置变化来模拟晶粒的生长,为焊接熔池组织的模拟提供了新思路。重点介绍了模型假设和模型的实现,并对此模型进行了评述,提出了模型的发展方向。
The GBE model for simulation of grain structures in welding pool is introduced.This model focuses on the evolution of the grain boundary between neighboring grains.Assumptions of the model and numerical implementation are presented emphatically.The model is reviewed and its limitations are analyzed.
