工程强度设计规范中的塑性准则将分四讲加以介绍。第一讲是近代工程强度设计规范的发展概况,指出塑性理论的应用是强度设计规范的基础性突破。第二讲介绍塑性设计准则中所依据的两个塑性力学基本理论——极限分析与安定性分析。第三讲讲述应力分类和应力评定问题。第四讲列举若干压力容器构件及其它机械的塑性设计实例,旨在说明这一设计准则的应用现状。该讲座的目的是向广大工程技术人员介绍和推广塑性准则,使之设计出更加经济合理、安全可靠的工程结构。
The plasticity criteria in engineering strength design specifications will be divided into four parts to introduce. The first is the development of modern engineering strength design specifications, and pointed out that the application of plasticity theory is a fundamental breakthrough in strength design specifications. The second part introduces the two basic theories of plastic mechanics based on the plastic design guideline - limit analysis and stability analysis. The third talk about stress classification and stress assessment issues. Lecture 4 lists a number of pressure vessel components and other mechanical plastic design examples designed to illustrate the application of this design criteria. The purpose of this lecture is to introduce and popularize the plasticity guidelines to the majority of engineering and technical personnel so that they can design a more economic, safer and more reliable engineering structure.
