在2000财政年度，一项为期3年的腐蚀管道试验计划开始了，其目的是：1）确定根据现行抗震设计规范设计的腐蚀管道的抗震安全裕度，2）澄清腐蚀核管道的弹塑性响应和极限强度。计划对腐蚀管道部件和腐蚀管道系统进行一系列试验。本文介绍并分析了这些试验的结果，重点讨论了薄壁部分的形式和数量对管道疲劳寿命的影响。Copyright © 2003 by ASME
In FY 2000, a 3-year testing program of eroded piping was initiated with the following objectives: 1) to ascertain the seismic safety margins for eroded piping designed under the current seismic design code, 2) to clarify the elasto-plastic response and ultimate strength of eroded nuclear piping. A series of tests on eroded piping components and eroded piping systems was planned. In this paper, the results of those tests are presented and analyzed, focusing on the influence of the form and the number of thinned-wall portions on the fatigue life of the piping.Copyright © 2003 by ASME
