| Abstract: | Through the study about frequency and modal for failure of crack form in structure, this paper applying finite element emulatio method, obtains the influence of crack and crack position on the structure frequency and modal, summarize the general regularity of dynamical state in structure with crack.The conalusion is obtained that it is possible to diagnose failure through variation of structure frequency and modal. |
