随着生产和科学技术的发展,断裂力学这门新学科近二十年来发展很快,它对工程构件的安全设计和选材原则提供了新的理论基础。为了使断裂力学广泛应用于建筑机械化等行业,本刊特约请清华大学力学教研室杨宗发副教授开设“断裂力学讲座”。“讲座”简明扼要,清楚易懂,便于读者了解断裂力学的基本理论和应用。“讲座”共分六讲:第一讲、线弹性断裂力学,第二讲、弹塑性断裂力学基础,第三讲、断裂韧度的试验测试,第四讲、断裂力学在疲劳问题上的应用,第五讲、应力腐蚀断裂,第六讲、断裂力学的工程应用。
With the development of production and science and technology, the new discipline of fracture mechanics has developed rapidly in the past two decades. It provides a new theoretical basis for the safety design and material selection principles of engineering components. In order to make the fracture mechanics widely used in construction mechanization and other industries, we specially invited Associate Professor Yang Zongfa of the Department of Mechanics, Tsinghua University to hold a lecture on fracture mechanics. “Lectures” are concise and clear, easy to understand, and easy for readers to understand the basic theories and applications of fracture mechanics. The Lecture is divided into six sessions: Lecture I, Linear Elastic Fracture Mechanics, Lecture Two, Elasto-Plastic Fracture Mechanics, Lecture Three, Experimental Testing of Fracture Toughness, Lecture Four, Application of Fracture Mechanics in Fatigue Problems , fifth lecture, stress corrosion fracture, sixth lecture, engineering application of fracture mechanics.
