影响构件持久极限因素的讨论

A Discussion on the Elementseffecting the Protracted Linit

本文重点讨论了工程上各种因素对持久极限的影响,其中包括应力集中、构件尺寸、构件表面加工精度、腐蚀介质等,以便在工程设计中尽可能减小各种影响,设计的构件更合理、更实用.

The article mainly discusses the effects which various elements on the project will have on the protracted limit,such as concentration of stress.component size,precessing precision on the surface of the components and corrosive medium,etc.so that we can make the effects as little as possible, the designed parts move reasonably and move practicaly indesigning.
