本文给出了一种分析循环载荷下带孔扳弹塑性应力应变的方法。从运动强化模型出发,采用可用性系数和屈服强度增量的概念,导出其循环瞬态特性的描述公式,并纳入了一般弹塑性计算的轨道。计算中不但可以应用增量法。也可采用比较节省机时的全量法,最后,通过相应的实验说明方法是可靠的。 In this paper, a method to analyze the plastic stress-strain of the hole-pull-in-tube under cyclic load is presented. Based on the concept of kinematic hardening model, the description of the cyclic transient characteristics is derived using the concept of usability coefficient and yield strength increment, which is included in the orbit of the general elastoplastic calculation. Calculations can not only apply incremental method. Can also be used to save the machine when the total amount of law, and finally, through the corresponding experiment shows that the method is reliable.
