摘　　要：针对弹塑性复合金属材料的断裂问题,提出了一种基于内聚力模型的一维弹塑性复合金属材料有限元模拟方法,并借助有限元软件Abaqus,以一维弹塑性复合金属材料杆单轴拉伸为实验背景,对两种循环加载过程进行有限元模拟,验证了该方法的准确性。Regarding to fracture issue of elastic-plastic composite metal material,a finite element simulation method of one dimensional elastic-plastic composite metal material based on cohesion model has been put forward,meanwhile applying with finite element software Abaqus,and taking one dimensional elastic-plastic composite metal material rod uniaxial tension as experimental background,two cycle loading processes have been conducted finite element simulation to verify accuracy of the method.
