你将学到

本综合教程深入而实用地探讨了断裂力学和循环载荷下的疲劳行为。它首先全面回顾了所需的理论概念，例如应力强度因子、J积分、能量释放率、滞后能量和损伤累积，然后引导您完成实际应用。 Abaqus/标准 和 Abaqus/Explicit.

断裂力学和疲劳寿命预测的基本原理
如何建模 分层扩展 使用 虚拟裂缝闭合技术（VCCT）
应用 巴黎法律 循环载荷作用下疲劳裂纹扩展
使用 XFEM （扩展有限元法）在二维和三维裂纹扩展问题中的应用
塑性应变和滞后能的作用 低周疲劳（LCF） 造型
实际应用 关键词编辑 增强 Abaqus 功能
块体材料（例如焊点）和界面（例如复合材料分层）的疲劳模拟

笔记： 本软件包是之前发布的两个软件包的合并版本：

Abaqus中的断裂力学模拟
Abaqus中的疲劳仿真
您将获得两者的全部内容——现在已无缝整合，可实现更深入的学习和更高的价值。.

研讨会 1：分层扩展模拟 | 基于 VCCT 方法的低周疲劳分析

本课程首先对复合材料在低周疲劳下的分层扩展进行完整模拟。本次研讨会将采用虚拟裂纹闭合技术（VCCT）结合Paris定律，模拟混合模式弯曲（MMB）试件中疲劳驱动的裂纹扩展。您将学习如何构建模型、施加周期性载荷、进行关键词编辑，以及提取裂纹长度和能量释放率等实用结果。.

研讨会 2：基于扩展有限元法的二维裂纹扩展

本次研讨会将使用二维矩形钢试件，通过扩展有限元法 (XFEM) 演示裂纹如何在没有预设路径的情况下扩展。这使得学习者能够模拟裂纹扩展路径未知的复杂裂纹行为——这是现代断裂力学中的一项关键技术。.

研讨会 3：经典方法裂纹模拟

本次课程采用传统的裂纹建模方法，讲解如何使用经典的断裂方法模拟钢材中的二维裂纹。重点在于计算J积分，并应用轮廓积分法从力学角度理解裂纹驱动力。.

研讨会 4：三维扩展有限元裂纹扩展

本文利用圆柱形钢模型研究了三维裂纹扩展。通过应用最大主应力准则，模拟预测了裂纹在载荷作用下随时间推移的扩展情况。该实例介绍了扩展有限元法（XFEM）在三维问题中的高级应用。.
