内容简介

本书系统介绍了断裂力学的基本理论和应用，涵盖了从经典线弹性断裂力学（LEFM）到弹塑性断裂力学（EPFM）的发展。首先，书籍回顾了断裂力学的历史和基本概念，引入了Griffith能量平衡方法、能量释放率及应力强度因子方法，探讨了裂纹稳定性及路径等问题。在此基础上，书籍扩展了LEFM至小规模屈服条件，分析了裂纹尖端奇异性、非线性弹性断裂机理及塑性区影响等因素。进一步地，书籍介绍了EPFM，包括裂纹张开位移（CTOD）、J积分及其实验测量方法，并分析了裂纹生长阻力曲线、J控制断裂及裂纹扩展的约束效应。此外，书籍还探讨了材料损伤和典型断裂特征，如微观缺陷的影响、材料强度及断裂可靠性，并通过微观力学方法分析脆性与延性断裂机制。最后，书籍详细讨论了金属、高分子、陶瓷及复合材料的断裂行为，为工程应用提供了理论指导。
