讨论用数值模拟预测板材成形中发生拉深损伤破坏的两种不同的求解方法。第一种是采用完全耦合的弹塑性破坯模型的动力显式数值方法。基于状态参量的不可逆热力学过程 ,完全耦合的本构方程考虑各向同性强化和拉深。这些已引入有限元软件ABAQUS/E用于对金属成形的模拟。在数值技术方面 ,隐式积分方法被用来对本构方程的局部时间积分 ,动力显式技术用于求解总体平衡方程。第二种方案是采用简化的损伤模型的方法 ,被称为逆法 (InveseApprch)。I.A被限定在考虑各向同性强化和损伤的塑性全量理论基础上的简单的本构关系。做比例加载和临界损伤达到以后的损伤饱和假定 ,可以得到损伤演化方程的封闭解。这两种损伤模型在编程中的实施采用两种方式 :计算中考虑或不考虑损伤作用 ,也就是耦合的或非耦合的计算。文中给出一些算例来说明每种损伤模型的优点 In this paper, two different methods to predict the damage of deep drawing in sheet metal forming by numerical simulation are discussed. The first is a dynamic explicit numerical method using a fully coupled elasto-plastic billets model. Based on irreversible thermodynamic processes of state parameters, fully coupled constitutive equations consider isotropic strengthening and drawing. These have been introduced into finite element software ABAQUS / E for the simulation of metal forming. In numerical techniques, the implicit integration method is used to integrate the local time of the constitutive equation and the dynamic explicit technique is used to solve the general equilibrium equation. The second approach is to use a simplified damage model approach, known as the inverse method (InveseApprch). I.A is limited to a simple constitutive relationship based on the plastic total mass theory of isotropic strengthening and damage. Do proportional loading and critical damage to reach the subsequent damage saturation assumption, you can get the closed solution of damage evolution equation. The two damage models are implemented in programming in two ways: computations with or without consideration of damage effects, that is, coupled or uncoupled calculations. Some examples are given to illustrate the advantages of each damage model
