    摘要:

    蠕变力学是一门悠久而又年轻的固体力学分支。为各种在高温、高压和其它严酷环境下工作的部件,如压力容器、管道、涡轮叶片等进行设计选定尺寸或估计有效服役寿命时,蠕变力学有重要的理论与实践意义,其任务是处理一些困难而严酷的工程问题。 本文综述蠕变力学的主要进展,包括四个部分: 1、蠕变研究的历史活动;2、蠕变研究的最新进展;3、常用的应力分析计算方法;4、蠕变破断与失稳。希望本文对于青年学者和工程师们有一定参考作用。

    Abstract:

    Creep mechanics is an ancient as well as a young branch of solid mechanics. It is of practice and theoretical importance to the structure and machine desiges in choosing the work-piece dimensions and estimating the effective service life of the heat-resisting parts, such as the pressure vessels,pipings,turbine blands,or variously structural parts, protractedly operating under high-temperature, high pressure, and other harsh environments. The major task of creep research is to solve such knotty and severe engineering problems. The present paper surveys and briefly reviews the major advances of creep mechanics. It inclucles four main parts:1 Historical activities on creep mechanics;2.Some recent results in creep research;3.Several computational methods of stress analysis in common use;and 4.About creep rupture and failure. We cherish the hope that it might be of some sevice to the youthful scholars and engineers.
