| Abstract: | Measuring method and present situation of creep damage are summarized. The relations between creep damage degree and resistance are analysed in creep process of metal material. A measuring method of creep damage has been put forward. The feasibility of judging the degree of creep damage is analysed and described in constant current power V A method measuring resistance system. |
