Title
(EN) METHOD OF DIAGNOSING THE LIFETIME OF STRUCTURES AND SYSTEM FOR DIAGNOSING THE SAME
Abstract
(EN)

The present invention relates to a method of diagnosing the lifetime of a structure and a system for diagnosing the same, the method comprises a step for preparing a structure to be measured; a step for measuring an amount of exothermic or endothermic heat of the structure; a step for measuring an amount of entropy decrease of the structure by using the measured amount of exothermic or endothermic heat; and a step for diagnosing the remaining lifetime of the structure from the measured amount of entropy decrease.
