教学目标
Course Objectives
断裂力学是固体力学的一个分支，研究含裂纹物体的强度和裂纹的扩展规律。它不仅在培养学生系统
掌握力学的科学概念、分析方法，构筑完整的力学知识体系方面占据相当重要地位，而且可以培养学
生对物理问题建模分析和解决问题的能力。
断裂力学教学强调清晰的物理概念以及与工程实际的密切结合。
断裂力学的基本内容包括线弹性断裂力学、弹塑性断裂力学、疲劳与应力腐蚀、橡胶与高弹体的断裂
力学的基本概念与应用。
Fracture mechanics, a branch of solid mechanics, studies the strength and reliability of crack-containing
material and structures and the propagation of cracks. It provides training in terms of scientific concepts,
analytical skills, as well as the capability of developing and analysing and physical models in real-world
problems.
Fracture mechanics emphasizes both clear physical concepts and engineering applications.
Fracture mechanics covers the topics of linear elastic fracture mechanics, elasto-plastic fracture mechanics,
fatigue and stress corrosion, fracture of rubber and elastomers.
