针对数值模拟材料损伤开裂的现有方法——空单元技术和嵌入过程区中结点力释放方法 ,提出了释放空单元内结点力的新模拟方法 ,既可解决原有空单元技术未曾明确的残余应力的释放问题 ,又可避免采用嵌入过程区方法时所引入的大量重叠结点。己有算例表明 ,本方法具有模型简明 ,操作便利的特点 Aiming at the existing methods of numerical simulation of material damage cracking-empty cell technology and the method of releasing the node force embedded in the process region, a new simulation method of releasing the node force in empty cell is proposed, which can not solve the problem that the original empty cell technology is not clear Of the residual stress release problems, but also to avoid the use of embedded process area method introduced a large number of overlapping nodes. Examples have been shown that the method has the characteristics of simple model and convenient operation
