摘要
Abstract
The thermal stress of skirt structure was analyzed based on cyclic thermal-mechanical loading.The ratcheting failure was assessed through elastic core criteria and elastic-plastic stress analysis,the fatigue failure was assessed through max-min cycle counting method and elastic stress analysis.It can provide reference for the protection of skirt structure against complex cyclic loading.关键词
