介绍利用扰动状态概念进行的有限元数值模拟方法。阐述基于扰动状态概念有限元法的应变平均化方法、解的收敛性和单值性、解对局部化问题的适宜性及其具有避免虚假网格相关性的特点。通过实验对该有限元法的计算结果进行了验证。研究结果表明,基于扰动状态概念的有限元方法具有传统方法所无法比拟的优势。 The method of finite element numerical simulation using the concept of disturbances is introduced. The method of strain averaging based on the finite element method of disturbances state is introduced. The convergence and univariate solutions of the solution, the suitability of the solution to the localization problem and the characteristics of avoiding the false grids are also presented. The results of the finite element method are verified by experiments. The results show that the finite element method based on the concept of disturbances has advantages unmatched by traditional methods.
