This course is intended for Graduate students, assuming that students have both a basic knowledge of the engineering
2 / 4 2020.04 materials and Material Mechanics. The course will begin by developing the theoretical framework for the fracture and strength of solids (e.g. theoretical cleavage strength, shear strength, Griffith theory) and then developing an understanding of brittle and ductile fracture. Then the techniques for the measurement of strength and fracture toughness will be presented, with a focus on the indentation technique, which is one important method for scientific research. In addition, this course will also present the basic concepts on the material strengthening and toughening (e.g. phase transformation toughening, composite approach, Eshelby theory, etc), as well as fractography. The course will also give students the recent research findings on the materials fracture or strength. This course will use several engineering materials, such as high temperature superalloy, thermal barrier coatings for areoengine, fiber reinforced composites, nuclear fuel particles and light alloys, as examples, to introduce the knowledge of engineering fracture, for example, the creep, fatigue, stress corrosion and Hydrogen brittleness induced failure. The course will be interactive and there will be periods for students to raise questions and discuss aspects of their own experimental work with the instructor. *教学大纲 (中文) Syllabus 周次 教学内容 授课学时 教学方式 1‐3 1. 材料强度与断裂基础 1.1 理论抗拉强度 1.2 理论剪切强度 1.3 应力集中理论 (Inglis Theory) 1.4 Griffith 理论 1.5 韧性断裂 1.6 脆性断裂 1.7 断裂韧性概念 1.8 韧性‐脆性转变 6 直播/课堂 讲授 4‐5 2. 材料强度与断裂韧性测试技术 2.1 强度测试 2.2 断裂韧性测试 2.3 纳米/微米压痕理论 2.4 影响材料强度和韧性的因素 2.5 强度断裂统计方法（Webull 统计） 2.6 案例分析 4 直播/课堂 讲授 6‐7 4. 材料断裂与增韧 4.1 裂纹形核机制 4.2 断裂形貌 4.3 脆性材料增韧机制 4.4 相变增韧 4.5 纤维增韧与复合材料 4.6 Eshelby 理论 4.7 工程材料设计 4.8 强度中的尺寸效应 4 直播/课堂 讲授 8 答疑/期中测验 2 课堂答疑/ 期中测验 9‐10 5. 蠕变与疲劳断裂 5.1 塑性变形 5.2 位错密度 4 直播/课堂 讲授
